It's not just MG and it's not just wireless though. While I wait for my XPower to float its way round from China, a friend lent me their Mini this weekend, complete with wireless Carplay. At least 3 times, I've had to remove and add my IPhone as Carplay just froze.. They've all got their issues, just so complicated nowadays.
The Mini also refuses to go into drive sometimes if you've dared to do something out of the ordinary, like turn it off and not get out. Open door, shut door, start again and it works

Computers with wheels, fun fun!!
