I'm thinking about buying an etrex20 like yours. My question is; if you lose your GPS signal, can you still nivigate with the maps, or does the whole thing go blank?
William.-
It is very very unlikely that you will lose a GPS/GLONASS signal for any length of time. The etrex supports both GPS, the american worldwide system plus GLONASS the Russian worldwide system. If you lose signal say in dense tree cover it will be a tens of seconds at the most. The map will stay on screen but there will be a delay in your position being updated. Hardly ever noticeable.

I've never lost GPS signal ever, except for inside of a tunnel, in all years of using it
