rockjeep92314 Posted April 14, 2008 Report Share Posted April 14, 2008 My unit has been working great. This weekend I was watching a dvd and needed to use the map. I put in the nav disk and it says its the wrong disk. I reset it several times and its still the same. Any tips? Please help. Kory Quote Link to post Share on other sites
Fracken21 Posted April 16, 2008 Report Share Posted April 16, 2008 Yeah, get a new disk, it's probably scratched. I've replaced nav disks many times b/c of scratches, sometimes they say they're not the right one, other times they just stop functioning half way through searching for an address. You can download the 70mtp here and burn it yourself, or just buy one off ebay. Quote Link to post Share on other sites
