2005 Expedition Adding a newer Factory Navigation Unit
I have a 2005 Expedition that has RSE, and the 6 CD Changer in dash unit with the audiophile sub. This was the year they did the switch to Phase II plugs(which I have).
My question is, can I put a newer Factory Navigation Unit in the vehicle and retain all that I have in there now?
I have been searching, but have not been able to come up with an answer.
Thanks in Advance
