It déjà vu all over again for car owners with new iPhones (7 7+) and iOS upgraders to iOS 10 with audio problems.Two years ago, with the release of iOS 8.0 there serious Bluetooth problems that were fixed with various software updates or other means such as the nuke-it fixes. Previous fixes don’t as well for some, while some have resorted to restoring iOS 10. Some contend it is a GSM interference issue while others say it is a hardware issue with early model iPhone 7 models. This time, BMW acknowledged that there are issues.

So far, a possible solution for audio streaming problems is to put the iPhone in airplane mode, and connect with Bluetooth according to one commenter. It appears to be a GSM interference issue. We are trying to figure out if the problem doesn’t occur for non-GSM carriers such as Verizon or Sprint. Therefore when you report problems, please include your wireless carrier.
The first fixes are the “nuke-it” fixes which involve deleting settings and starting over again from scratch. These work if the Bluetooth signature has been corrupted during the update process. Updating through Wi-Fi or iTunes seems to help prevent Bluetooth signature corruptions.People have gone as far as disconnecting the car’s battery to get Bluetooth functionality to return.
The next possible fixes are:
- Enable Airplane Mode, then turn back on Bluetooth and Wi-FI. The bug for music streaming, reportedly is caused by interference with GSM cellular signals. A reader reports that this works. However, in theory in Ariplaine Mode, you won’t be able to make phone calls.
- Disable Handoff on iPhone – launch the Settings app from your Home screen ▸Tap General. ▸Tap Handoff & Suggested Apps ▸Toggle Handoff to Off.
- Change Bluetooth Settings– Go to General ▸ Accessibility ▸Car Audio Routing ▸ Select “Bluetooth Headset” instead of the default Automatic.
- Delete/Reset the Vehicle’s Bluetooth Settings – we have reports that by removing the fuse for the infotainment unit for a few seconds and then re-pairing the updated iPhones, it then allows the Bluetooth to work again. A variation on this fix is to disconnect the car’s battery for a few seconds to lose the stored data and then re-connect the battery and re-pair the iPhones.
- Restore iOS 10 – some believe that iOS 10 was not installed properly on iPhone 7/7+, restoring iOS 10 through iTunes it may help.
- Connect through USB or AUX – for playing music in BMW or other vehicles, you can connect with the AUX adapter or through USB to play music.
- Replace iPhone 7 through warranty – we have one report that when a car owner returned the iPhone 7 and received a new one it worked with his car. However previous reports with early iPhone 7 manufacture dates, there was no difference.
The BMW website shows compatibility for only up to iPhone 6S +.
