I am having a serious problem loading topo maps from my computer onto my GPS. I have been at it for at least 2 hours - probably more - and in that time have loaded two topo maps onto my GPS (had three ready to load). The rest of the attempts elicited a response of "This device already has your latest maps fully installed" even though I have one topo that is yet to be loaded (also gave that message on my first attempt). I am thinking this may be a computer problem and not a "transfer" problem. I never had a problem of this nature with a previous computer. Any ideas? Thanks much.
I haven't been able to upload maps from my (new) computer, with Windows 10, onto my (Etrex 30) GPS. I get the dreaded message "no unlocked files were found for this device" when I plug my GPS into the computer. If it matters; I'm not sure it does, I had no problem with my old computer (Windows in transferring files onto my GPS. Any guidance/ suggestions you may have to address this problem will be appreciated. Thanks much!
