I currently use a Garmin Oregon 550T along with Max OSX Lion, Basecamp, MapInstall and MapManager.
Back in August I downloaded a .gmapi file containing the maps for a particular country. Installed it no problems whatsoever.
I have recently downloaded further .gmapi files for a couple of different countries. When I go to MapManager and install them, it comes up with the usual question asking me if I want to install, so I click install. It tells me that it has installed ok. Everything seems ok so far...
Anyway, when I go to MapInstall I select my connected device and click next. Then on the next page in the drop down arrow to select maps, the only map available to me is the one I installed back in August; OSM World Routable (12-08-2011).gmapi. It does not even show that I have the other maps installed on the computer. They are a similar name but have a -1, -2 and -3 after the date e.g.; OSM World Routable (30-09-2011)-1.gmapi.
Can anyone advise me how I load all these maps on to my device?
