Just updated my iPhone 6s to iOS 11 and the Bluetooth connection with my car (Renault, using R-link 2) has stopped working. They connect automatically, but a few seconds later the connection is lost. Then they reconnect again and lose connection again. Over and over again. I've tried everything I can think of: Rebooting both the iPhone and car. Re-pairing devices. Resetting the phone to factory settings. Updated car software. Even tried to shut down my Apple Watch, so it didn't interfere. Nothing helped. Everything worked perfect yesterday before the update. I use the car+phone 2 hours every day, so I'm desperate to get it fixed. Anyone knows what to do?
