I am still trying to mess around with the whole 3d thing. I was reading the thread "About Garmin Additions files (gmap3d-JCV-gmaptz-ASR-G2S" but I could not find the gmap3d.ing on my garmin so I decided to reinstall my maps through garmin express and then the gmap3d.img showed up under systems in the garmin and I also have the map layer to show 3d and terrain. Now for some reason mymaps shows three different types of maps: Cnna - Na-Dem North America DEM, CN North America NT 2015.30 3D, CN North America NT 2015.30 ALL. Should there be check marks next to all three of these maps? Do you think you could show me a screen shot of your 2595 with terrain/3d?
