I sometimes have the CarPlay issue where the song is "Playing", you can see the art of the song and the seconds running but there is NO audio. No matter what you do. You have to turn off your Mustang, and start it up again.
You have to specify that your car is a rear wheel drive. Because the Mustang is, they’ll either send a flat bed truck or they will put little wheels on your rear wheels so that your transition and differential don’t get messed up.
I did NOT break mine in.
I was told by many Ford mechanics that the engines are already broken-in at the factory. When they build your V8 Coyote engine, they stress-test it and they run it at high RPMs at the factory for several minutes. (This is concerning the engine and not other vehicle parts)
