I just got an etrex 20 and I'm doing my best to figure it out (as I am rather computer stupid...). But one thing I simply cannot figure out is why sometimes it shows the relief map, sometimes it's just a plain blue background (even in the same location). It is always set to "show shaded relief when available," and I've tried toggling that on/off, powering the whole thing on/off, etc. When I first bought it and had no maps on it (except the base maps it comes with) the relief didn't show up at all (just blue background) then when I loaded a state topo and the trails map from here the relief showed up...now it's gone again and nothing seems to have changed. Is there something I'm missing?? It seems like it should be something simple...
Has anyone else had this problem? Any suggestions?
I'm using a Mac if that matters.....
Thanks so much for all the great help, advice and tutorials...I couldn't have even gotten this far without it.
