The current versions of iOS 8 is creating problems for people who pair their iPhones with Bluetooth devices, particularly car audio systems, according to complaints. In the case of cars, devices with the firmware may refuse to pair, fail to play audio, or disconnect when a phonecall comes in. The problem can’t be solved with iOS 8.0.2, and is affecting many automotive brands, including BMW, Ford, Hyundai, Toyota, and others.
People may also have trouble pairing with other Bluetooth accessories such as speakers and headsets. Apple is said to be aware of the bug, and working on a fix; meanwhile, however, a temporary workaround may involve signing out of iCloud, forgetting Bluetooth devices, and using “Reset All Settings” and/or “Reset Network Settings” before restarting a device, re-pairing it, and signing back into iCloud. The Reset All Settings command is potentially dangerous though, because some users have reported losing all their iCloud Drive documents.
