In my f900bt i have connected my ipod with a brand new belkin a/v cable.The cable in my pc works,in the car denies.It shows on the screen that the connection failed and on the ipod screen that it is not supported.I have connected my ipod also with the usb cable and the audio RCA and worked.Any ideas on how to make it work?

sounds like the ipod doesn't like your brand of cable, the avic doesnt care what brand you use, return the belkin and try a different brand
