Hi, I have a 2689lmt, a 2598lmthd and two 2595lmt's. I downloaded some Idaho topo maps from GPSFile Depot awhile back and installed them to a micro sd card. The files show up in my maps as cgpsmapper version0095. They show the contour lines on the GPS. I added some new topo maps from the same site but I don't know if they're going to show up. They didn't show as the cgpsmapper version. They did show as Oregon topo after I installed them using Basecamp. I won't know for sure until I take a drive in to Oregon. There's a check mark in myMaps on the GPS plus a check mark by Topo U.S> 100K v5 so I think that they will show up. Jim
