I have been looking at the Garmin products and was really interested in the Montana 650T, until I went to the store to actually hold it in my hand and see if I could find the property I needed it for. I want to build some new trails on our property and wanted to see it in TOPO form. I found it easy enough but when I zoomed in on it all it showed was a white background, all of the contour lines were virtually gone. The 100K topo map was useless. For this unit being top of the line I would have thought they would have good maps loaded. Are there any sugestions other than paying for 24K maps. I am not sure that would make much difference either. Thanks Steve
