i was wondering since my new car stereo player has an USB port, and i can finally resolve my iphone battery issue on long trips, if i charge my iphone through the car stereo player USB plug, would it eat up much of the car battery? since its charging and i may be using 3G network for GPS all at the sametime? i got a kenwood brand car stereo player for 130 bucks at best buy, any suggestions?
today i just installed a new car stereo player with an USB port built in...?
