phone will not link with car’s bluetooth after new ios 11 download. Music however will play. what’s the proplem? Everything worked fine before the upgrade.

I figured out the problem. Delete device from phone and unpair from auto. On my Toyota’s steering wheel, there is a phone off hook symbol and a talk symbol, press both together. The system will give you a list of options, select setup. Next option choice select pair phone. During pairing select play through car’s system. This worked for me. Originally I selected Bluetooth set up instead of pair phone, this was causing the error phone “not linked “. Using the setup option on the aux option on the stereo screen never gave me the option to pair phone. Hope this is helpful.
