Troubleshooting a Map that is Locking Up or Slow on an Outdoor Handheld

Additional mapping, such as Topo 24k and Topo 100k, on an outdoor handheld GPS may not display correctly or not at all if the 'Worldwide DEM Basemap, NR' is disabled in the map settings. If the map isn't being displayed properly, ensure the Worldwide DEM Basemap, NR is enabled.

Enabling the Worldwide DEM Basemap, NR:

1. Select Setup from the Main Menu
   
2. Select Map
   
3. Select Configure Maps
   
4. Select Worldwide DEM Basemap, NR
   
5. Select Enable

Once the Basemap has been enabled, the map will display as expected.

The 'Worldwide DEM Basemap, NR' comes installed on many of Garmin's handheld devices which displays major roadways, state and country boundaries, and major geographic boundaries. The unit switches between the TOPO mapping and the Basemap when zooming the map out so you can pan the map to view other locations without waiting for the device to draw all the topography lines in the area. A slowly drawing map or freezing of the device can be a result of the Basemap being disabled.
