I deleted the gmapprom.img because otherwise there was no space for the new map. While copying the new (hacked) Map the unit froze. I had to reset the unit by pressing the reset button. After that the navigation won't boot. The radio functions are ok but when I access the navigation only the text 'Navigation' appears and nothing else.
I looks like the navigationsoftware won't load. The software freezes during the load process. I only see the Garmin startup logo.

During the boot process the unit is shortly recognized by f.i. Webupdater. After a few seconds when the Garmin bootscreen is there, the communication gets lost again.

Who knows a way to access the unit again an to recover it. I trid updating the firmware using a SD card and a CD; sadly not recognized. I also tried several keycombinations while booting. I can enter the test-mode (FNC+ATT+reset) and the change splashcreen (FNC+VOLDOWN+reset). I tried also holding the screen at different places but no change.

Garmin support (repaircenter) says the Naviboard has to be replaced; there is no software cure.

I suppose the original firmware has been loaded during manufacturing before there was any software on the flash. I think there must be a way.

Who has an idea? Any help is very appreciated.

I had a problem like you.
