First off...yes, its an Apple factory cord. So I've got a C3...and I'm hooking up the iPhone with the USB cord and when I detach it leaving the car, the phone is pretty warm...today I got a warning on the phone for 'excessive temperature'. i was just wondering if anyone else in the forum has experienced something similar. I still can't figure out how to keep the iPod app from starting when I plug in the cord. I'm not running the Entune app...I'm just not in the mood for it all the time...although it did work well calling out traffic on the San Diego Freeway in LA.
