So I have a scosche usb car chager from back when I had an iphone. I've been using it with the sync cable that came with my incredible and Its been charging ok. Kinda similair to a usb trickle charge. Anyway I take a trip and use nav and play a little music and I'm blasting the ac so I'm sure the phone is not overheating as its sitting on my center console. The phone drains dead even while plugged in. I just ordered the incredible compatible car charger from Motorola on this site and have heard of some car chargers not having enough power does anyone use the Motorola chargers and nav android does that work? Anyone use scosche and nav and have probs?
