alpine cva-1000 cd changer select

Hello, well my problem is with the cva-1000, i cannot select cd changer on the screen all it has are fm1,fm2,am, and nav, but no cd changer option. how do i get that option to show up on the screen, ground a wire or what im stumped? Oh and there is what seems to be a yelow rca input on the brain but i dont think that it is a rca video input. If you know what that is for let me know.

                                                                              Thanks,  Jared

if any one out there can help us out i'd be most greatfull. i am having the same problem as well. i purchsed the ai-net to RCA adapter, however the CVA-1000 will not display this as a input source.  what have i missed? do i have to enable the ai-net port as an input source? if so, how??

thanks in advance
