In my last post I skipped over the part where after I downloaded the map to the 2gb card in the card reader I loaded into the rino. I then fired up the rino and after it acquired the satellites I went to the map page and zoomed all the way in and out several times and did not see any sign of topo maps. At that point I started trying to open the files to see if there was any difference in the status. As far as what maps I see when I turn on the unit there only seems to be the preloaded garmin map. No sign of any topo maps.
