Three months using my iPhone 8 with my SR+ connected via Bluetooth. Two hours spent last couple days without the car connecting to the phone. All troubleshooting steps performed, natch. Last desperate move was to Reset All Settings on phone, still no go. I don't even get the number code sent to verify connection. I'm carrying an iPod Mini in the frunk; car tells me it connects to that, but that's irrelevant. I have a friend who's far more knowledgeable than I, and he can't figure what the problem may be. Maybe a service issue for Tesla?
