What exactly is the correct way to install a map from BaseCamp to my eTrex 20? (My GPS unit is just new and does not have any micro SD card installed.) I used MapInstall to install a Michigan TOPO map to my GPS and it seemed to work fine. Now I am trying to add a New Jersey TOPO map as well for an upcoming trip. Both maps are in BaseCamp and work as expected there. Following the same procedure as I did for MI, NJ appears to work (MapInstall shows installation complete), but NJ TOPO does not appear on my map list on the eTrex. Do I have memory issues? Nothing in the owners manual that I can find defines the memory available or the capacities of micro SD cards that will work.
This is anything but straightforward!
