So I've noticed that with my Carplay, if I plug in the iPhone before the head unit is fully initialized (the Nav has to be fully initialized along with the radio, which it seems if left on XM takes longer), that my Carplay will constantly force the head unit to switch over to Carplay from other functions (very annoying).
Anyway, I noticed that on cold start (like vehicle is left off overnight), that the head unit takes a bit of time to fully come up. Vs, a few hours later, it seems to start faster.
The other day, I had to put some stuff in the trunk (in the morning, so "cold" start), so I'd opened the liftgate and put stuff in and then got into the car and started it.
The head unit was like all set to go in seconds.
It seems that if you open a door or something it somehow "fires up" in the background, the head unit.
I tested this by the next day by simply opening the drivers side door and left it open while i fetched the paper from outside (vehicle was NOT started yet), got in the car, started it and again, in seconds, the head unit was all set to go.
