Hello! I understood that you could actually play your iPod feature of the 3GS over the bluetooth system in the car. Can't figure it out in the Toyota Tundra we have. It syncs for phone calls, but can't get the music to play and am not sure what setting to have the stereo on. I can't set it to "AUX" without having it actually plugged in...but I thought I could get this to work somehow without having to actually have it plugged into the car stereo. Was I confused (quite possible) or does anyone know what the heck I mean and how to do it?
