I've downloaded ca. topo and cawild twice.. they are on my pc but can't get them to show up in any garmin programs..mapsource,basecamp etc..What am I doing wrong?
Have you run the installer (.exe file) for each map?The process should look like this: http://www.gpsfiledepot.com/tutorials/how-to-open-maps-in-mapsource/
Are you running Windows 7 64 bit? If so, see this: http://forums.gpsfiledepot.com/index.php/topic,3343.0.html
MyTrails is here: http://www.gpsfiledepot.com/maps/view/53/
However, there was also this which was never resolved (or else "Mylar" just never followed up)... http://forums.gpsfiledepot.com/index.php/topic,3390.0.html
