Re: Ford Escape 2007 Navteq map updates?
As you have discovered, the CD-based navigation technology is obsolete. When Ford offered update CDs, they cost over $200. It's doubtful that there is any relationship between the later DVD system and the CD-based system.
Now you can get a portable and update-capable GPS which is many generations ahead of the CD-based nav system for ~$125. Aftermarket GPS companies like Garmin update their road/POI maps about 4 times a year.
Since many cell phones have navigation now, in-car GPS devices may soon go the way of in-car fixed-mount cell phones.
