Why Bluetooth iOS 9 issues with iPhones 4S/5/5S/5S/6/S+ are fewer than iOS 8 in cars but could cause problems

iOS9screenAs usual, with iOS iPhone updates, there are reports of Wi-Fi disconnection problems, problems downloading the update to iOS 9 and cellular data problems with different carriers. Turning functions on and off or resetting iPhones often help. Last year, there were major problems with the iOS 8 update and in-car Bluetooth connections with infotainment systems that persisted with each update. The questions remains, “When should iPhone owners update to iOS 9?”

There are few reasons to wait, busy servers can cause glitches in the software update. Although there are millions of iPhone owners and there has been months of beta testing of iOS 9, you’ll have to decide for yourself if the update is worth the risks of losing functionality. So far, there have been fewer Bluetooth connection problems reported with iOS 9 then there were with iOS 8, last year. However, with only two days of updates, it may take time for iPhone owners to realize if iOS 9 works with everything in their vehicles.

Update 11/08/2015:Our readers and forum members have noted some problems with Bluetooth and iOS 9.1 with some Pioneer Systems, Ford, Mercedes-Benz, Nissan, VW, Kia, Porsche, Subaru, BMW, Mazda and Chevy models.

Update 9/24/2015:Our readers have noted more problems with iOS 9 such as:

  • 2013 Honda CR-V with Bluetooth disconnections for voice calls or music,
  • 2015 Cadillac XTS with SMS not working.
  • 2014 BMW 5 series connected to iPhone 5s with iOS 9 update, the Bluetooth control doesn’t work and owner can’t change songs.
  • Honda Civic 2013 Audio works however it  haslots of issues with calls they get consistently transferred to phone instead of being handled by Bluetooth.
  • 2012 Fiat 500 Sport Blue & Me there is no sound once caller picks up.
  • 2011 Chrysler 200 and a 2013 Ram both with uConnect lost Bluetooth connection after IOS9 update on iPhone 5C.
  • iOS 9 on iPhone 5 will not connect to my connect in Ram 1500.
  • 2005 Acura TL won’t connect to iPhone 5 with iOS 9.


The first thing to consider is that it usually takes up to an hour to upgrade, not just the downloading of the software but checking to make sure that your apps all work. We suggest that you update to iOS 9 during a time when you do not need your iPhone to work and you are not planning to use Bluetooth in your car/vehicle.

The Apple servers were very busy on Wednesday when the update was released. We see forum comments with these iOS 9 update problems:

  • iPhone 6 stuck for 24 hours now. Tried turning it off and on and power button and menu button to restart but still stuck.
  • iPhone update taking 18 hours to download.
  • Silent Siri without sound, text only.
  • News app not working on iPhone 6 but works on iPad.
  • Lack of directions in Maps.
  • Contacts not showing in spotlight search.
  • Siri not working in British English.
  • Problems adding photos to albums.
  • Problems pairing Bluetooth to Macbook Air.
  • Thousands of unread emails showing up in mail.
  • Notes destroyed.
  • News app not working.
  • Contact names missing from text messages.
  • Visual voicemail not working after upgrade.
  • Unable to hear or end phone calls.
  • Phone overheating in pants causing blisters.

As far as car related Apple forum discussions we found the following of interest to car owners.

  • Ford SYNC system was stuck in continuous call, when Ford SYNC software was not up-to-date. After, a few days of problems and  the SYNC update, the Bluetooth worked.
  • Our reader reported than an iPhone 5 with the latest Apple updates and Bluetooth doesn’t work on a 2005 Acura TL.
  • Bluetooth is not working with Mini Cooper Coupe John Cooper Works and update did not help
  • Bluetooth not working on Octavian VAG.
  • iPhone 6 connects to 2015 Honda Civic fine, senders information on the text message doesn’t show.
  • Problems connecting 5S to Peugeot 30.
  • Problems with VW Golf and VPN calling.

Support form forum members suggests:

  1. Check your car stereo’s user manual for steps about pairing with a Bluetooth device.
  2. On your iPhone, swipe up to open the Control Center, then tapBluetooth icontwice to turn Bluetooth off and back on.
  3. Restart your iPhone.
  4. On your iPhone, unpair your car stereo. On your car’s display, unpair your iPhone and any other devices. Restart your car and your iPhone, then pair and connect again.
  5. Update your iPhone.
  6. Install any firmware updates for your car stereo.

Reset Network

Bluetooth problems can sometimes can be fixed with through Network Settings.  Go to Settings > General > Reset > Reset Network Settings. Your iPhone will not know the Bluetooth device and you’ll now have to reconnect.

The ultimate fixes are the “Nuke-it-fix” or off your Handoff,” for iPhone iOS Bluetooth fixes.

Reasons to Update to iOS 9

A good reason to upgrade is there is a security update that stops a vulnerability that allows someone to install malicious apps on iPhones and Macs via the Bluetooth-enabled Airdrop filesharing feature. Anyone in range of a targeted device with the feature enabled could plant malware on the iPhone, even if the victim didn’t tap “accept” for the offered file. iOS 9 places a “sandbox” around the Airdrop feature to limit its access rather than address the underlying vulnerabilities. So far no one has reported getting hacked through the vulnerability.

iOS 9 New Features Valuable to Car Owners:

  • Improved battery life.
  • Better Siri.
  • iO9 Bluetooth Disconnect -With iOS 9, there is new option to disconnect Bluetooth from the iPhone easily.
  • Wireless CarPlay – iOS 9 will have wireless CarPlay and support for auto manufacturers to develop apps within CarPlay.
  • Better Maps with Traffic – iOS 9 displays real-time traffic updates and an approximate time it will take to reach the usual destination through Apple Maps notifications on the Lock screen.

We have had a report form our readers that iOS 9 beta fixed a Bluetooth issue with his car, which is a good sign.

Should you update ASAP? It depends if it is clear that your car make and model will work as well as other important connected devices you use with your iPhone. Before doing anything, make sure you allow enough time for glitches and also make a backup of your files, settings and be patient.

Last year, we learned that in general, the older the car, the more difficulty, there can be with Bluetooth connections. Older car owner may want to wait to see what happens.

The “Nuke-it-fix” and its variations of the “off your Handoff,” continue to work for some Bluetooth fixes.

If you have updated to iOS 9 for iPhone 5/5S/5c 6-6+ 6S/6S+ and it fixed or fried your Bluetooth issues or music streaming with your in-car infotainment system, please let us know in the comments below, be sure to note your make, model and year of your vehicle. We also welcome any solutions you have found worked with your car.

We have comments from readers that there are still Bluetooth problems reported with BMW, Audi, Acura, MINI, GM(Chevy, GMC, Cadillac, Buick), Honda, Kia, Toyota, Volkswagen, Mercedes-Benz, Mazda, Lexus, Fiat, Hyundai, Chrysler, Acura, Mazda and more.

Previously, after talking to many automakers we asked Why Bluetooth iOS 8-8.1 & iPhone 6-6+ issues persist in cars? It seemed like the 8.1 update helped with a few new model cars. Here is a summary of Bluetooth issues and fixes and checkout the most popular nuke-it fixes.

  1. I have Iphone 6s+ IOS version 9.3.2 connected with Seat Leon 2015. It was working fine till last friday. Now when I connect the phone with the car, it causes a failure on the easy connect system and software seems to be crashed on the car. Easy connect system restarts itself after 10 seconds including radio and etc. This continues untill I turn off the bluetooth of the phone. Any ideas?

  2. I have a 2012 Honda CR-V and my iPhone 6 will no longer play music through the car but I can make phone calls through it. Help!!

    • Try removing the phone from the car and removing the Honda from your Bluetooth settings and re-pair to see what happens.

      You can also contact Honda for support.

    • I have the same issue with my 2013 Civic EX L The Honda dealer gave me a link to check out to see if my phone was compatible. The site says its not. News Flash! I knew that 🙂

  3. 2013 Convertible Beetle TDI.
    Radio works fine until I hit Search to Google something. The radio goes silent and the phone icon appears in my car screen next to the Bluetooth icon. Once I close Google, the radio continues playing. No issues with making or recieving phone calls though.

  4. Thanks so much for this! 2012 Mini Countryman, intermittent phone audio since iOS 9 update. All re-pairing & ‘forgetting’ had failed until finding this thread. Setting BT to headset and deleting my Withings Watch from BT menu on phone, then reinstalling, seems to have worked! Thanks so much, local dealer & Apple had no idea. So grateful!

  5. I just had my radio replaced under warranty in my 2013 Hyundai Elantra GT because of the 15 minute cutoff on phone calls. When I left the dealership, I paired my iphone 5s ( with the latest 9 update). Later that night, I tried to make a call on my way home and the radio system started having trouble . If I tried to make a call, the radio system froze and then completely turned off. I was so upset that I would have gladly put up with the 15 minute cutoff problem on the old radio rather than this new set of problems. Since it was late at night and I could not call the dealer, I started asking questions on the web and found this site. Thank you for all the posts.
    changed the accessibility from automatic to Blutooth headset under General settings. Someone said that did not solve their problems so I also disabled handoff found under General settings. This seems to have solved my problems between the car and the phone.
    I do not use a lot of the phone features, so I had already turned everything off that I could find –like cellular data, wi fi, siri etc. I just wanted to be able to have handsfree calling and now it works.
    Thank you for all the posts. I was really really upset. I guess the dealerships and Apple can’t keep up with all the technology communication problems between devices.

    • I’m glad it helped. The problem may be that with too many features turned-on on the iPhone the processor gets over-loaded. The hand-off feature caused problems with even Bluetooth headsets.

  6. My 2012 GTI worked fine with my 6+ for almost a year and one day it just quit working. I can connect my phone just fine, and I can make calls JUST FINE. But any sort of music and NOTHING COMES OUT OF THE SPEAKERS. I’m beyond aggravated with the entire set up.

  7. My iPhone 5S with iOS 9.2.1 was connected to my MINI Cooper 2013 for 2 years, no problem. Then one day two weeks ago it just stopped being connected.

    My MINI registers on my iPhone, but when I try to connect it from the car it just says “Searching…” and never finds my iPhone.

    The MINI dealer says it’s a bug with Apple and they’re waiting for a fix. But now I’m unable to make/receive calls over Bluetooth. Anyone else with this problem?

  8. Ghetto you all removed my post because I gave a shout out to a morning show I don’t even listen to.

    I had posted of my problems connecting to my BMW after patching 9.2.1 but I got mine to work at lunch today. I tried countless times to connect this weekend, all to no avail. Today at lunch I connected my phone via an Apple USB and now paired. Here’s how all of this went down:

    1. Last week updated my Iphone 6 to 9.2.1

    2. Could no longer connect to Bluetooth in 2015 BMW M4

    3. Tried every recommended fix that I could find – resetting network connections, removing devices, hard phone resets etc.

    4. Patched Beta 9.3 – still did not work

    5. This weekend then tried to pair using a knock off Apple Lightning cord (I use this as my regular charger) – no luck

    6. Today I tried again, however, this time using a legit Apple USB and I am now paired.

    7. Thank you pairing gods.

    I don’t know if anything that I’ve done over the past few days somehow set me up for today’s pairing, but I DO know that I’m now paired to my M’s bluetooth.

  9. 2016 Jeep Renegade, Bluetooth is connected but when I try audio streaming from my iPhone 6s it plays through the car speakers but you can barely hear it even with the volume all the way up

  10. Wissam says:
    my old iPhone 5 was working perfect, now I have IPhone 6 plus and I have a Bluetooth problem in my car, when I make a call I hear nothing but the other hears me. I tried all the above advices in order to fix the problem but I failed
    p.s. the weird thing that there is no problem when I make a call through viber and whatsapp.

  11. my iphone 6 with version 9.2.1 will not play music through my 2013 cadillac CUE system. No problem with my old phone (iphone 4) but now when I look to play my music the CUE system does not see any play list. The phone works (can make/receive calls) but cannot play music. Anyone know a fix for phone to play music through the cadillac CUE?

  12. Were you paid to post the header of this thread as I think it totally misrepresents the issue with Bluetooth and the new versions of IOS

  13. Dear Srs, I have an iPhone 6 and since the update to IOS9 the connection to BMW320 from 2014, is very strange because is is connected and I talking well and suddenly it disconnected for a for a couple of seconds and reconnect again and is doing this for entire call, how can I fix this, can some one help on this, please, thanks best regards

    • Have you been able to fix this problem? My husband and I both have had the same exact issue for the last several months.. Really since the IOS 9 updates. We have Mazdas, two different models and years…we both have iPhone 6, I have the plus. I haven’t been able to find a way to resolve this issue. We have both tried deleting the phones from the cars, and deleting the cars from the phones, as well as trying to see if the newer Apple updates will fix.. Nothing. Any suggestions would be much appreciated. It’s so frustrating to be talking, and then randomly disconnected, and connected, and so on…

      • One thing many people miss is shutting off the Handoff feature it seems to clog up the iPhone bandwidth and memory. We covered it some of our articles. See buttom of this article.

        Also turning of Siri seems to help some peole.

  14. I hava en iphone 4s, 8 months ago it stopped working (bluetooth) in my car! 3 months ago, wi-fi didn’t work! He didn’t recognize any wireless spot available. I read on the web and I found people saying that put in the freezer for 10-15min.
    Wellm I put my iphone in a Plastic bag first for 5min (i was affraid) and he didn´t work! Then I put 12 min and it Worked!!!! Now he gets wi-fi… One week ago I tried in my car the bluetooth and NOW it works also in my car!!!! WTF!!!

    • This one we’ll call the iPhonesicle treatment. I’m wondering if the issue had to do with overheating or sensor stuck on hot.

  15. iPhone6 upgraded to iOS 9.1 and iOS 9.2 with Audi Q3 MMI (2016 model) present the same issues: long time to pair the devices, noise during phone calls, jumps in audio streaming

  16. 2012 Mazda 3, iPhone 6 with updated iOS 9.2 it will not even find my car Bluetooth while it is searching for bluetooth.

  17. 2015 EOS Bluetooth doesn’t work at all for both of our phones iPhone 6S . The car does not locate any phone within range. Nothing at all! The cord that comes with car is for the older model iPhones 4-5s which worked fine.

  18. 2016 Hyundai Elantra. Iphone 5s – worked for 2 1/2 months prior to update. completed 9.0 and 9.1 updates and it stopped working shortly after. It pairs and shows calls connecting but unable to hear caller on the other end. They can hear me in the car but I can’t hear them. I have tried disconnecting and repairing several times. Also tried changing from automatic to Bluetooth – no luck. Would love some assistance. Dealership blames iphone.

  19. Bluetooth running in iOS 9.1 on my iPhone 6 drops constantly. This happens on everything, not just my car, although that is the most aggravating.

    Sometimes it will drop mid “song” when I am in my car (2013 Lexus GS 350). When that happens it is all over. I have to stop, put the car in park (it has to be stopped to do this) and delete the phone as a device, then reinstall/pair the car and the phone. The first time this happened I went to an Apple Store. They were no help, told me it was my car. I called the dealer. They never heard of the problem, but they would be happy to trouble shoot it, just drop it off. Well, since I needed my car and didn’t have time to go through the foolishness of dropping it off, I experimented. I found the key was that the car was in park. It has happened a few times since, but is more aggravating than it is difficult.

    Is is the one that makes me sad that I upgraded to 9.1. I listen to books on audible.com in my car. It used to be simple, now, not so much. Anytime I do ANYTHING, I drop the connection. Same thing with Amazon Prime music. Play an album, ok, switch to playing songs and at the end of the first song I have dropped the connection. The books are all business books and occasionally I want to hear a passage again. Audible has a backup button. Touch the button and it drops the connection. This is even true of a Bluetooth speaker in my house and my Sound Rise clock radio.

    9.1 is very disappointing.

  20. I have Kenwood DDX372BT. Bluetooth worked great until iOS 9 update. Today, I’ve talked to Apple support and they basically said that they cannot help me and implied that Kenwood needs to update their system to accommodate iOS. So the fact that few months ago I’ve spent money on car stereo with Bluetooth connectivity being the major reason for purchase, didn’t really concern them. I’ve also asked if it is possible for me to go back to previous version of iOS to which reply was no. Tech Support basically said it sucks for you and they are not going to do anything about it.

    • just saw the comment about the changing accessibility from Automatic to Bluetooth. I did it. If didn’t work at first But then I again
      Forgot the Device and tried again. And it worked.

  21. Well after a week of trying everthing including disconnecting car battery, AND having spent nearly 2 hours at the Apple store (goes through what’s on internet, then says call manufacturer!), we nearly gave up.
    At home whilst discussing the issue, my son who used to work in mobile stores in his University days overhears and pipes up ” why don’t you change the settings in accessibilty to Bluetooth headset?” Now everthing works great.

    So the settings are – General>Accessibilty>CAr Audio Routing and select “Bluetooth Headset” instead of of the default Automatic.

    Looks like there is a bug in the Automatic setting.

    P.S. there are a few threads with this problem, might help to almagamate them.

    • Thanks that was the first time we heard of changing to the headset setting. We’re sorry but comments go with the original post. However, if we find that more people say that changing the setting to headphones works, we’ll do a whole article on the subject. Tell your son he’s brilliant and thanks!.

  22. I have a 2014 VW Passat and up until 2 weeks ago my phone worked fine using blue tooth and playing music. Now My sounds such as ring tones and such as well as my phone calls work through bluetooth but my videos and music through both iTunes and amazon will not play. The screen on my phone will show that the music is playing but nothing is coming out of the speakers. Incredibly frustrating. My husband’s 6+ works perfectly fine.

  23. 2012 Honda CRV & iPhone 6+ with IOS 9.x : Issues with bluetooth dropping and reconnecting resolved by turning OFF wifi. Just turn off wifi and report back here if it works or not with car/phone details. Lets see if this is the culprit.

  24. My BMW 535 F11 ( 2012 ) doesn’t show the phonebook from my iPhone 6 plus. very irritating.
    and the voice control doesn’t work either.

  25. 2015 Honda Civic Iphone 6 plus with Newest IOS Wile on calls Iphone Disconnects and reconnects multiple times during calls

  26. Toyota 2012 Corolla…upgraded to new iPhone 6s on Thursday, new phone connected to Bluetooth just fine (never had an issue with iPhone 5c). Updated iPhone OS at work on Friday to 9.1, cannot get it to handshake with BT at all.

  27. 2013 Hyundai Veloster

    Pairs with vehicle, but upon opening the vehicle’s Pandora app, phone is disconnected. Once it is disconnected, phone is no longer discoverable without turning both the device and vehicle off and starting over. Still able to play music via “Phone Media” instead of Pandora.

  28. 2014 Ford F-150 – IPhone 5s running iOS 9.0.2 Bluetooth connects phone perfectly but won’t stream audio via the Bluetooth stereo input. Under Bluetooth devices, the phone symbol is lit, but the music note is grayed out. Never had a problem before iOS 9.

  29. iphone 5s with 9.02 not connecting with volkswagen, bmw, or pioneer nex 4000. No sound when dialing a number. Siri works and BT audio transfer works.

  30. Problem: Phone drops bluetooth connection while make calls in car.
    Car: Honda Pilot 2015
    Phone and IOS Version: iphone 6 -IOS 9.02

    1. Delete iPhone device profile from car phone.
    2. Delete bluetooth link setting from iPhone for car phone.
    3. Turn bluetooth setting to “off”
    3. Go to iPhone Settings> General> Reset > select “Reset all network settings.”
    4. Put wifi password back into phone.
    5. Do a two finger “hard reset” on iPhone.
    6. Boot phone back up.
    7. Turn bluetooth back on.
    8. Re: pair iphone to car
    9. Test by make a call and allowing to just set “live” for 5-10 and check for connectivity drops.

    Will let you know in a couple of days if it continues to work. So far no drops.

    • Hi Shawn,

      Does it still work….if I reset “reset all network Setting” nothing else will delete….what do you mean by “two finger “hard reset” on iphone” Thxs for your help Vince

  31. 2013 Tahoe using 6s 9.0 that connects fine but can’t use Siri or voice commands cuz phone ties to connect to Bluetooth and voice command times out. Any advice

  32. I have a 2015 Ford Focus SE and the 9.0.2 update worked for a bit and then completely broke again. Doubt the dealer will do anything about it, Apple just doesn’t know how to update their own OS without breaking other functionality.

  33. After uprading iPhone 5s to IOS 9 and 9xx iPhone will not sync on 2015 Ford Fusion. It won’t sync on my wife’s 5s with IOS 8, either. Judging by all the problems reported by folks, Apple has blown it again. I am thinking seriously of going back to android phones.

  34. I updated to IOS 9 and then IOS 9.1, I have a 2013 BMW 3 series and now my google maps will not automatically pair to the speakers with Bluetooth. I never had this problem before and it worked in my old 2007 3 series. Can anyone offer any advice. Its a small thing but very irritating.

    • I just chatted with Apple, and they say the engineers are on it. Should be addressed in the next ios9 update. I also emailed BMW. I can’t believe they are still three versions behind, at iOS 6. Sheesh… But yeah, I’m having the same issue. Everything was fine with my iphone 5s.

  35. Bluetooth problems with Chevy Equinox 2013, it keeps dialing no # and you hit hang up and it keeps doing it, for now just left not paired but would really like a fix.

  36. Bluetooth not discoverable for Blue Parrot VXi B350-XT ver x801p bluetooth headset on iPhone 6S. Strangely, it DOES work iPhone 6 (both on iOS 9.01). Does the iPhone 6S have different bluetooth specs?
