I keep seeing new Dodge Nav Radios for sale on eBay... Started to make me wonder, just how hard would it be to upgrade from the standard single CD 4 speaker system up to a functional Nav system?

Anyone know what parts would be needed? Also, does anyone know if there is existing wiring in place for this setup, or would I have to procure/fabricate a new harness or section of a harness for this to be functional?

 

All the wiring is there, just make sure you get the antenna. You should not have to add any wiring...

 

you need the new bezel too
