I have a PSone hooked up to the Line input of my Sony MDX-C6500R head unit but the source button one switches between MD and radio. How do I get to hear the PSone through my car stereo? I know about the XA-C30 CD changer control, but how does this tell my head unit to play sound from the Line input? Any ideas?
If you check some other threads, then you'll see that that in the accessories forum a huge list of people hooking up a PS2 to their car. You oughta find your answer in there.
