any can tell me... if this will work with my avic d2, i already have a dvd player hooked up... is there other placess i can hook this aux cable ?

There is only one A/V input on the D2. You could use the CD-RB20 to get audio into the AVIC. This is a RCA to P-Bus interface for audio only. Would be selectable through the source screen.

totally understand but would i have to unplug my dvd player...and just come with the ip bus cable from that blue port fromt he back... then connect to my zune...
