I decided to update to new maps and now I constantly get "insert appropriate disk"
I did all the searches and found how to get into the service menu and when I view the "version check" it lists the current versions. System program, Application Program, but under GPS program it lists NG. I have tried numerous times to force write the GPS Program. When I attempt to force write it, it shows...
1. PC ATA Card = NG
2. Disk = Version 4.40
So I click on number 2 and hit the map button to force write the program and it starts for about 1/10 of a sec then says....
DVD - Flash [ ng ]
I have tried to and succeeded to downgrade the programs back to the original disk but it never works for the GPS program it just shows NG. It does work for the System Program and the Application program.
I viewed each of the disks and and can see the neccessary gps program on the disk but just can't get it to load onto the unit.
Any help or suggestions would be greatly appreciated. Thanks
