After about four years each with an iPhone 4 and 6 I just got an 11 because my iPhone 6 was nearing its end. All is basically well except for one aggravation: it pairs with my 2010 Tundra BT and plays audio (various iPhone sources) via simple BT or line in, but the actual phone function won’t pair. So I can’t send or receive phone calls through the Tundra. I’ve deleted all devices from the Tundra and repaired my iPhone + powered the iPhone off/on but no change. Tundra audio will playing from my iPhone will “pause” when I make a call but not pick up the phone signal. Phone is iOS 13.3. Small problem I know but if anybody has a fix I’d love it. I make probably 90% of my longer calls from my truck!
