When in Garmin Express and going to "Manage Maps", my Topo US 100k and Southwest Topo 24k maps are not being shown. My 700i has them listed, and I can toggle them on/off and verify that the map layers are loading onto the GPS unit itself. At least I can use them, but how do I manage these two maps? I initially thought, no problem I can just reformat my SD card and that will delete them. Turns out I have the Topo US 100k saved to the internal storage...so anybody have any suggestions on how to remove this map from the 700i? Reformatting the SD card got rid of the 24k map, it no longer showed up as an available map on the 700i. I decided to reload it onto the GPS using Express, it is again available to select when using the 700i, but does not show up in Express. I'm assuming I am missing something, but shouldn't the Topo US 100k and any 24k map be showing up under manage maps within Express?
