I’ve read differing information regarding if your phone needs to be -lugged in to use the SYNC3 system. It seems to me that Bluetooth would be used, as that has been a technological expectation for. Quite sometime. It seems unlikely that a vehicle coming out in 2020, wouldn’t be able to handle Applecar play with Bluetooth but SYNC4 will, according to reports. I’m confused about if phones need to be plugged in to use certain phone functions. Anyone know?
