I went thru the process of downloading 10 maps to create 1 gmapsupp file.
When I put it into my etrex 20, and try to select a map, I'm seeing (displayed) only 2
of the map names. I enabled both. I tried viewing some tracks in states other than
the states that were displayed, and the map data for those states displayed OK. I thought all the states on the gmapsupp file would display. And if only one displays because it is a single gmapsupp file, why am I seeing 2 map names that can be enabled/disabled?
Is that just the way it works??? Thanks!
