Neil, thanks for hanging in there. What I am trying to do: Step 1) Start MapSource (6.16.3 patched) . Step 2 select the detailed area(s) to send to the GPS. Step 3 Click on transfer to device (usb stick with only root directory, and 1 sub-directory, Garmin). Step 4 run gimgunlock on the gmapsupp.img file (i have been running from command prompt to check for error msg just seeing ignore statements) Step 5 start sendmap20 (6.7 Pro). Step 6 try to add the gmapsupp.img to window by drag and drop and the add map button. No matter what I do, nothing appears in sendmap20's window. Stuck, cannot send map to GPS
New process (try work around) step 10 start sendmap20. Step 2 Add maps from uncompiled map directory. maps appear in sendmap20's window (map name tels me if I want it or not finding maps by trial and error) step 3 compile maps using create gmapsupp.img button. Step 4) run gimgunlock on gmapsupp.img to unlock. Step 5) remove previously added maps from semdmap20 Step 6) using add mapbutton, add the gmapsupp to sendmap20 window which does work. Step 7)send map to GPS, GPS can use the maps and does not give maps are locked response.
Next to try: try generating gmapsupp on computer that feeds my other GPS V which has been unlocked normally, and see if sendmap20 will add that gmapsupp to it's window (after unlocking of course)
