Ok I could not get the bypass to work in my truck for my D3 so I am looking at going a diffrent route. Can I put in a DVD changer. I already have a 12 cd changer installed. Can I do both? I am only seeing one IBus plug in the back of the D3

You will still need to do your bypass correctly to watch any video source while in motion.

But the Pioneer changer is the XDVP6. Its on their site

Thanks, It looks like I will have to figure out the bypass
