Mac user (10.9.3) - Like the cleaning lady said: I don't do windows.
Upgraded my nuvi 3590 LTM using garmin express 3.1.5.0
to the latest software and maps (north american) 2015.10
Updated nice and fine on the nuvi as far as I can tell.
But it didn't update the maps in basecamp (installed via app store - 4.3.1 ).
Been reading up a bit about this - seems the common response is to use mapupdater but that one wants to install old maps only (not the 2015.10).
Finding the maps downloaded by garmin express (~/Library/Application Support/Garmin/Express/Maps/NA.2015.10/IMG/.../City Navigator North America NT 2015.10.gmap) and having mapmanager 3.0.1 "install" them actually does copy the file to basecamp maps directory (~/Library/Application Support/Garmin/Maps/City Navigator North America NT 2015.10.gmap) but basecamp utterly fails at seeing it as installed...
So am I now condemned at trying to downgrade the maps on my nuvi in order to get the same map data on my mac and on my nuvi ?
Or is there hope still ?
I understand Garmin not wanting to give away maps to everybody, but it is quite silly to not let those of us who actually have a license use it due to these restrictions.
