OK - I'm going a bit nuts with this. I upgraded to 8.0 and started losing connection to my iPhone 6 but it would reconnect. Then 2 weeks ago, it stopped connecting at all. I forgot connections, rebooted the car and the phone and the two do not pair. Other phones connect to my car, so it must be me right? I have the latest OS. I found an article on the Tile causing problems, which I had. Removed it and nothing. I brought the car into Tesla repair and tried it on 5 cars - 4 with 8.0 and 1 with older 7 OS. 7 worked fine. 2 of the 4 8.0s connected. Techs couldn't figure it out. Weird. My phone has been working with my car for 2 1/2 years. Brought the Phone to Apple - all diagnostics showed that bluetooth / radio was fine. Apple tech recommended wiping the phone, which I did. Still no pairing. I'm 10 hours into troubleshooting here and still can't make calls from the car. Any other suggestions?
