Greetings, I own an iPhone 4 and love it. Been using Mapquest GPS for directions and find it great. My question is can someone tell me a compatible in dash for the iPhone 4? I've noticed alot say they work with iPod but very few say iPhone. I would very much like to have charging and audio playback. If was using iPhone's iPod and Mapquest for audio directions would they come through the stereo as well? The radio will be going into a 2 speaker cargo van so I'm not too worried about sound quality / performance. Thanks Kevin L. Mister880 If you are going to fly----They Fly with US Airways!
