I am having trouble playing music on the Avic-F90BT with the Iphone 3G. The syncing of the song tags install correctly. It shows the songs on the interface, but I cannot get it to work at all in terms of the volume. It seems as tho it is put on mute, but it doesn't say the volume is down on the settings. I also tried to use Apple ipod usb adapter, and I still don't have any luck. Does anyone know the solution?

ya.go to av source and change av1 to ipod.

Also make sure you have the audio RCA connections from the pioneer ipod cable hooked up. For whatever reason, some people have assumed that it wasn't necessary to hook those up.
