I just bought 5 D3's for my 2006 town car limos. I was wandering if I can get a Nav pic on my rear screens. Is there a mod I can do to get this output inside of the unit. I was a 12 volt tech for 15 years so I know my way around the inside a a radio. I talked to a few people and there not to fimilar with these units. Thanks

Why can't you just use the video out jack on the back of the unit, and run RCAs to the screens? I have only done a few D3s so far, none of which I connected to rear screens, but I do know that the navi screen can be output to rear screens on the N2, I have done that. I have no reason to believe that you can't do it on the D3...

D3 doesnt display it's Navigation screens to an external source/monitor.

Agreed. Sorry

D3 doesnt display it's Navigation screens to an external source/monitor.

That specific reason is why I bought the older D2. I wanted to keep an eye on my boat.
