Hi, im brand new to droid.. in fact, I haven't even gotten my hero from fedex yet! (comes tomorrow). That said, im looking for a car audio system that hopefully WORKS with droid. This means: Plug in usb from car to usb on Hero: 1. to play mp3s on car speakers 2. To hear GPS nav voice on speakers from sprint nav 3. If possible use a mic built into the car unit & speakers for CALLS and things like auto pause music when call incoming. 4. Most importantly: USB charge the phone! I know this functionality is out there for iphone/ipod. Is there a car audio system that does this with droid? Also: I know I can get a combo of these things using bluetooth & aux ports etc. But I am hoping for simply get in car, cradle phone, plug in usb, listen to podcast.. Thanks!
