Hey there. I have an iPhone 3g that I want to dock in my car so that I can.. 1.) Output Audio Through the Dock Connector To My Stereo 2.) Charge My iPhone 3.) Mount It For When Turn By Turn GPS Arrives I can do all three steps, but I keep getting the GSM buzz when I use Edge. This happened with my old iPhone as well, but I could move it away from the stereo and only hear it every so often. I bought the cheapest stereo with an AUX about two years ago that has worked great....except this issue is annoying as hell. Ive used Ferrite Beads on the Stereo's input and output to very little avail. FOR THOSE OF YOU WHO USE THEIR IPHONE IN THE CAR, WHAT STEREO DO YOU USE...(Assuming its not the stock).... I'm going to try a new stereo and install a ground loop to hopefully stop the sound. While on 3G everything is fine; however, I only have EDGE at my University. Any suggestions are appreciated. Thanks guys!
