I just got a droid pro and i'm wondering if there is any way to play videos from my pro on my screen in my truck. I want to play music videos so I can use my sound system in truck. I don't think video signal goes through the 3.5 mm jack, I could be wrong. I do believe the mini-usb charger port pushes video, but again I could be wrong. Anyone know how to do this? And has anyone ever done it with another phone?
