I downloaded us topo 2008 maps from mapsource and I tried it also using basecamp on to my 450t. I selected the rectangles (map tool) and transfered the maps to my device. I go on my device and look at the map it shows only the rectangles i have downloaded (ok good). But when i zoom in on the rectangles with shows the map of the 100k preinstalled base map. How do you turn the 100k map off? How do you get the 2008 topo to show up on the map? And yes the 100k map is disabled.:confused:
thanks
