I'm not so sure about the battery problem. Truthfully I experienced something similar in my 07 when i first installed my original iPod interface with the factory radio. My dash went blank, no lights, mirrors, ect... Anyway it was diagnosed by my local shop, had them pull that interface and replace it with my current one, no problem since. So, not sure about what you have added to your truck, but if this is a new radio with an on-star replacement interface, or a factory radio ipod interface it may be worth the phone call. Check with the dealership, many times if they find the fault in the aftermarket goods, they will make you responsible for the diagnossis and repairs (removal of the aftermarket goods).

From my reading i found that to be a problem with a few brands of iPod interfaces for these trucks. I tried a couple till I found one from soundgate that works really well, still tough to navigate the iPod on my non-nav radio, but the truck works now. I also have a few other devices i use also, one for ZUNE, the simple plug and play iPod part from soundgate also and they all work well, no problems have popped up that I can see.
