I'm asking this question for my dad regarding his 2007 Expedition. It has the factory Navigation HU, and will not read the map disc.

We spoke with a dealer after trying to clean the disc and the reader. They said that the unit might be done, and that we could purchase a new disc to test if that would work but don't count on it. The truck was a month out of an extended Ford warranty when it started having issues , and it worked intermittently for about 8 months until now when it doesn't work at all.

Has anyone else had this issue? the dealer's reaction was that it was a fairly common issue. If it was under warranty they would have removed and put in a new one as it is not a serviceable part. Any tips for other ways to get it to work?

Where could we find this map disc if we were to try the test? We are a bit wary of paying big money for something that we can't return if its not the problem. Otherwise, where is a good place to find a new/used factory nav head unit for a reasonable price.

PS. In my understanding the NAV unit is identical to those installed from the Factory in 06-08 F150

 

I have a 2007 F-150 Lariat with the DVD nav and the exact same thing happened. Took the nav disc out, put it back in, and it errors nonstop now. The whole unit is a pile of crap, it ate a few of my friends CD's a while after this that I have yet to be able to get out. I am under warranty luckily so they are replacing it free of charge, but it's still a steaming pile of dung.

 

if they wont replace it you can always buy a aftermarket unit. alpine makes one with garmin maps loaded on a sd card. and when you need to update the maps you can either purchase from garmin and put on the card and call it a day or you can look for downloads for them.
