I am having an issue getting the maps to work on my unit. i downloaded some maps on the basecamp ( Minnesota topo and bwca maps) and they show up and i can see the layer on there. i go to install the map onto the unit and my sd card and it installs successfully( i just highlighted the areas that i am going to use so i dont have to wasted space). then once that all done i go onto my etrex 20x and go to layers to enable and disable what i want and only 2 of the 4 maps i downloaded show up and the 2 that are on there do not show up on the map even when it is enabled. any thoughts?
At the moment, most problems of this nature are the result of Garmin's defective software. If you are using Basecamp 4.7 and MapInstall 4.2, then that's likely the problem. These versions will not install maps properly, although everything appears to work until you try to view the map on the GPS.
