I have an 08 Explorer,Eddie Bauer, 4.0L, with the factory navigation and Sync system.

It keeps coming up with in-complete map data when trying to set certain routes, so I've been looking into getting the maps updated.
I found what I thought was a solution on Ebay. But all of the updates appear to be DVD, and our explorer only plays CD's.

Would I still be able to update the maps using the DVD? Or should I start shopping for a portable gps?

 

Well I went ahead and bought the DVD, and it does work fine. But I had to navigate through the settings to find out how to make it work.

I ended up going to Menu>System Info>Navigation maps. Once you are there it will ask you to open access for the Navigation DVD. Then the front of the screen will actually fold down to reveal a second disc slot and the old dvd will eject. Insert the new disc and then it will begin installation.
