Can anybody help?
I updated Nuvi 2599 to NTU 2015.40 device via GarminExpress , but noticed that gmap3d.img and gmapdem.img maps are missing. After removal of unnecessary files (voices, keyboards, etc) from internal memory I got about 2GB of free space (this with gmapprom.img present) and tried to update the map again but these 2 maps are still missing. I also looked at installed maps in ProgramData\Garmin folder on my PC and couldn't find them there as well. I copied gmapdem.img to SD card and device can see that map. I can't do the same with gmap3d.img because this file cannot be unlocked for Nuvi 2599. Any ideas how to get 3D map file on the device? Thanks.
