A few questions from a new owner

[SickSix]

Sorry if these are answered somewhere else, I searched and didn't find anything.
25 ST without "sun & sound" package

1. When I park and turn off the engine, the radio and screens are still on, and I can only roll up the front windows before opening the doors. Shouldn't the rear windows also be able to roll up/down when in accessory mode? Is that normal?
2. I can't change song/station with steering controls when the screen is on Android Auto rather than the home screen? Volume works, but not the channels on radio, Sirius, or USB. I'm not using Android Auto as the music source. Is this normal?
3. Does anyone else have the Perimeter Alarm as a dealer installed option? Mine came with it, but as far as I can tell, it didn't include the optional LED or shock sensor, so the only thing it really does is beep then honk the horn if you open a locked door from the inside. Trying to decide if it's worth asking the dealer about.

Thanks!

Found this in the owner's manual:
Accessory Delay:
The window switches remain operational for several minutes when you switch the ignition off or until you open either front door.
Sounds like every other car I've ever had, but this one doesn't apply to rear windows...
