The local shop installed my Avic D3 in a 07 Saleen and now the ipod is not recognized by the D3? I plug my ipod but I cant press the Ipod button on the Menu of D3? What is the problem? Thanks.

Posibly the cable isnt conncted properly in the back of the unit

Or maybe the cable is defective

That would be my guess

You are hooking it to the "ipod" cable correct? and not trying to just hook it into the front panel through the aux jack or something along those lines?

If youre in fact hooking it to the ipod cable and it doesnt work then Id suggest taking it back to your installer and complaining that they "posibly" hooked it up wrong
