MFM and MSM and Garmin BaseCamp on Mac OS X Lion

Sorry about the clumsy blog title, but I can't think of something else that clearly captures the essence of this post.

This may sound silly, but I had been wondering how to load maps into BaseCamp running on Mac OS X Lion. It turns out that all you have to do is plug in your Garmin GPS receiver (GPSr) via the USB cable and fire up BaseCamp. Wait awhile for the GPSr to boot and BaseCamp will detect and cache any maps it finds in your GPSr (it works with Nuvi and the 62s). The available map titles are displayed at the top of the left hand panel. Click on the map you wish to display and that's it! The maps take some time to load the first time around but are cached so it's really quick after the first time. You may wish to go to BaseCamp > Preferences > Advanced to allocate more disk cache.

Just when everything seemed to be working, I realized that BaseCamp was only detecting the NT North America and MalFreeMap (MFM)but not MalSingMap (MSM). I reinstalled BaseCamp and tried another GPSr to no avail. So it was time to figure out how to install MSM into BaseCamp on a Mac.
