I've got a problem with my N2, I can be driving along and it's like I drive into a lake or something the map drives into blue. Also the navigation will not navigate to anywhere using phone number search or any of the other ways. Any ideas?

Has it ever worked? Hpw long has it been in? Is the brain secured? Is the vss wire hooked up? What year/make/model is it installed in?

I had it do the blue thing once when it was in my truck a 2004 Dodge Ram. I removed it a couple of months ago, then a buddy wanted it so we put it in his 2001 Ford Supercrew 2 weekends ago. Sometimes the map will work fine, but you can drive into blue. We thought it might be an antennae so we put in a new GPS antenae with the same symptoms. It hasn't successfully uploaded a navigation (won't tell you where to go). Also sometimes it asks for the disk to be inserted when it's already in the drive.

Wow. That's a lot of problems. None of which I've run into sorry bro. Maybe someone else might know.
