My reason for not using the front one is that it doesnt work. (never has)

and if those do work, how would i activate it so i can hook it up to my ipod and get music playing from it?

doesnt the D series have a video input, if so then this is where you need to connect the cable, and you would have to use the second cable linked to as the first one will not connect to the females

RCA's on the back of the unit

then you select the video input as the source, most units this will need to be activated for it to function.

Why not just get the ipod cable if your wanting to hook up your ipod?

i have seen some people that just dont like the ipods interface, and find it easier to just access the music from the device itself
