I have an 09 Ram with standard single CD unit. I also have a navigation unit out of a 07 Ram. does anyone know what wiring is needed. Or is the truck prewired to plug n play with nav unit.

 

I highly doubt it will just plug in. Plugs/Wiring are likely different.
Even if it DID plug in, you`d have to go to a dealer and have it lit up. (programmed to your truck)
Why dont you exchange them an let us know how it worked out for you.

 

I went back to the 07 Ram and took most of the wiring out. It had premium sound system and more. Holy crap,,,,,
Have it all layed out on the ground eliminating wires. Gonna try and get the CD, GPS and sat radio to work. Got it to light up so far. Ill keep ya posted
