Why iPhone 5-6S+ iOS 9.3.2 Bluetooth choppy connection problems with in-car radios will continue with iOS 10

applewatchbluetoothApple announced iOS 10 at WWDC with some new Bluetooth features. So far we can’t tell if iOS 10 will help the multitude of iPhone owners who have had problems connecting their iPhones to cars since iOS 8.0 -9.3.2. Bluetooth will be very important to the next generation iPhone 7 because in order to make the phone thinner the headphone jack port will be removed.

Apple announced that iOS 10 adds Bluetooth iBecaon printing, called AirPrint Bluetooth Beacon. The wireless printing is through a Bluetooth iBeacon or through a printer with AirPrint Bluetooth Beacon embedded. There may be a problem created for Bluetooth users if AirPrint Bluetooth Beacon is turned on when you enter your car. We have seen problems with the HandOff feature being enabled affecting Bluetooth connections. We are concerned that too many Bluetooth functions on iPhones will block the needed car functionality.

Let’s see where we are with iOS 9.3.2. The update was supposed to fix “an issue where some Bluetooth accessories could experience audio quality issues when paired to the iPhone SE.”

Here are the latest complaints and thanks from people who were finally able to connect Bluetooth to their cars:

  • Choppy Bluetooth connection with Toyota with 9.3.2, iPhone with 9.3.1 still works with car.
  • Choppy Bluetooth audio with 2016 GMC Terrain.
  • Bluetooth issues with 2016 Chevy Tahoe.
  • VW Golf 2011- sometimes the iPhone will say connected, then not connected, then connect again.
  • Ford Fusion Bluetooth drops at lease every 30 minutes randomly.
  • After update to iOS 9.3.2 can’t connect any Bluetooth device including car.
  • 2013  Honda Civic and every type of Apple device. None of them will maintain a connection. It has been happening since car purchase with a 5,6,6S,iPad
  • 2012 Honda CR-V with Phone 6 will no longer play music through the car but phone calls can go through it.
  • Hyundai Sonata 2013 & 2015 with Bluetooth connection audio for phone calls stutters. Every other word is heard. This is also on ringing so it isn’t just the remote connection.  Same problems with Sonata 2013 Hybrid Jeep and BMW and Ford Fiesta 2012 titanium mode.
  • 2014 Subaru Forester iPhone pairs with car but doesn’t stay paired.
  • There are also reports of choppy audio with Bluetooth headsets.

  • Audio won’t play in Kia 2011.
  • A user commented that a Ford dealer stated the inability to use an iPad with Ford F 150 with Sync is due to IOS 9.3 update. iPhone won’t connect with Ford Sync either.

  • Bluetooth issues with2016 Buick Encore, 2014 Mazda CX-9.
  • iPhone can still be paired with 2012 Kia Sorento, however the phone book does not download. It displays that it is being downloaded, but whenever the driver tries to call by name, it comes back that it does not recognize command. Other household iPhone 6S that is still on IOS 9.3.1 can be paired with same car and works fine.
  • 2013 Dodge Dart after update, the iPhone connects and will randomly play music a but there is absolutely no sound with calls. The driver can hear it ring and answer it on screen but nothing more.

We continue to get reports that versions of the “nuke-it” fix continue to help those plagued with Bluetooth problems, such as this variation:

  1. On the iPhone: Settings->General->Reset->Reset Network Settings. (This will reset your WiFi info as well, so be prepared. This will also change your phone’s name to “iPhone”.
  2. In the Car: Delete the old iPhone’s connection info.
  3. On the iPhone, change your phone’s name from “iPhone” to whatever you want it to be.
  4. Re-pair the car and the phone.

One of our readers noted “I have a 2010 Lexus HS 250 H. My iPhone SE with iOS 9.3.2 connected after I deleted all Bluetooth devices and reset network settings”

Another thanked us

“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 Bluetooth to headset and deleting my Withings Watch from BT menu on iPhone, then reinstalling, seems to have worked! Thanks so much, local dealer & Apple had no idea. So grateful!

“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. I changed the accessibility from automatic to Bluetooth 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.

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.”

iOS updates can change the iPhone handshake to Bluetooth. Updating iOS can alter the Bluetooth signature of the Bluetooth device that was used before. Let’s go over all the possible fixes just in case we missed something.

Beside the “Nuke-it” fixes, if you are having Bluetooth problems with iPhones is to disable the frequent locations feature in iOS that keeps checking for traffic to remind you when to leave for appointments.

Sometimes turning off Siri helps with GM model Bluetooth connections.RESTORE your iPhone using a full 9.3 install rather than an over the air update through iTunes.

Keep hands off the Handoff feature, just by turning off the HandOff feature some users have been able to connect iPhones to their cars, again. The other new fix is to use the car as “Bluetooth Headset”

Read all the fixes that worked previously and new ones.

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. My pandora loses connectivity at the beginning of every song. The next song begins to play and then it says “cannot connect to Pandora” and then reloads and starts to play again. This has been since my last update to ios 10.2.1 for my iPhone 5s in my 2016 Honda Odyssey.

  2. I had choppy audio via Bluetooth with Toyota entune and my iPhone. I would have to connect, disconnect then reconnect. I found that it went away as long as I keep the number of Bluetooth devices on my iPhone at 4 or less. As soon as I connect a 5th device, the problem returns. If I delete any Bluetooth device and top to 4, it works just fine

  3. I have the iPhone 6sPlus and since the last update my bluetooth connection between my phone and car (2008 Toyota Highlander Limited) is on again/off again. Sometimes it connects, sometimes not. I’ve re-“paired” the two and its worked. Then the next time I start my car it won’t connect. I drive down the road and suddenly its connected. There is no consistent rhyme or reason, its got a mind of its own. I’ve read the various “fixes” but it seems to me that Apple should come out with a fix so everyone does not have to go through this goat rope every time they get in their car.

  4. My 2014 Ford Escape SYNC will not voice dial since upgrading to IOS 10.0.2. I can call from “recents” or “contacts” through car audio but no voice dialing.

  5. 2010 Volvo S80. iPhone 5s on both 9.3.5 and 10.0. Calls are simply noise. On 9.3.5 bluetooth headphone calls are silent, music is working. On 10.0 bluetooth headphone calls are noise, music is working. Nuke-it or any of the other suggestions have not fixed the problem. Everything was working fine before ios 9.3.5.

  6. Just upgraded to iOS 10. My iPhone pairs with the car audio ok (Toyota Camry Hybrid 2015) but beams only phone calls (Whatsapp calls included). No music or audiobooks, actually no audio content, I even tried Youtube. When I look at the new music app’s feature below of playback device, only sees my iPhone is shown and no bluetooth device. Has anyone experienced similar? Do you have a solution?

  7. Just checked and my i phone 6 has been upgraded ios 9.3.3 so may be this is the blue tooth problem and hands free on the Hyundai ix 35?

  8. 2016 model Hyundai ix 35 – voice recognition on Blue tooth with an i phone 6 is up the creek. It simply does not understand what I say – so if I say ~Call Home it calls someone else who’s name begins with H and if I say the number it will not let me finish telling it the number it interrupts all the time and says say more numbers, correction or delete. If I correct it, it still comes up with the wrong numbers. Its exasperating – Does anyone else have this problem?

  9. Was having bad connections with my 2016 GMC Sierra as well as my Pebble. Nuking restored stability to both pairings.

  10. 2012 Ford F-150 (Sync). I frequently need to re-pair my iphone 6+ (about every 2 weeks on average)
