I purchased my 740i just yesterday, and have been playing with the electronics quite a bit while driving, and parked.

Today after driving to the gas station for a fill up (my wife in the car listening to music with air on) the car wouldn't start.

I had to call AAA for a quick battery jump, and the car was good to go again.

Is this common with these cars? Should I not be playing with the Nav, Cd's playing, phone, etc for extended periods if im not on a long drive?

I'm taking my car to get tinted tomorrow, and i'm worried the cars battery is going to be completely dead by the time the tinters are done.

Thoughts? Comments?

Do I need a new battery? Is that covered by the extended warranty? It's an 01 covered until 07...
