I have an 09 M3 coupe. My iPod nano is connected via the central armrest BMW cable that came with my car. Search did not yield answers to these questions:
1. How do you get it to shuffle all the songs on your iPod or on a particular playlist?
2. If I leave my iPod plugged in all the time, is it charging my iPod even when the car is parked and turned off, thus draining the car's battery?
