After reading the tutorials, I found a relatively new version of something called "Garmin MapManager" which was last modified in Feb 2010. I have downloaded the map manager, but would like to load in the programs from this site. Things like Icyrus USA and Canada, as well as the Northwest States are my most commonly used ones when using Mapsource on hte PC side. Given that there is actually a Northwest States MAC installer hosted on this site, I assume this must be possible. Can someone please illuminate the steps I am missing? Thanks.
to follow up, I successfully installed communicator I believe.
The MapManager program asks for me to install the NW Maps file, which I do, but it never wants to open it. Again, I still am missing something. Thanks Mac folks!
Once you've downloaded check out the mac tutorial: http://www.gpsfiledepot.com/tutorials/how-to-load-maps-on-my-garmin-gps-unit/#mac
