Thanks for all the replies. I am going to try it this morning, when I take my son to school!

I was going to try it last night, but I am afraid of trying the radio in the garage, while the car is parked. Doesn't it suck, that we have to be so afraid of the battery going bad? I am nervous to even open the door or the trunk, when the engine is not running! When the pedals were installed a few days ago, the driver door was open about 15/20 mins. I was freaking out about the battery. To be safe, I put the X5 on the BMW battery charger...and sure enough, it took over 24!!!! hours to fully show a charged battery. Just 15/20 mins with the driver door opened, pulled the battery down! Oh well...I guess since we know about this, we just have to be sensitive and aware of the issue. Luckily, the car is just SO awesome & everything is so great...we just have to deal with the crappy battery problem. Again, thanks for the iPod/iPhone replies, I'll post the results!
