Is you GPSr  NOT  in night mode?  Nor in 'auto' mode and being used after dark?

Did you install the mapset and use MapSource or BaseCamp to select and transfer data from the mapset to the GPSr?   See: http://www.gpsfiledepot.com/tutorials/how-to-open-maps-in-mapsource/   and   http://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/
