MS isn't supported by Garmin for quite some time. Better to use BaseCamp/MapInstall because some images generated by MapSource can have errors and you don't know which ones do until it's too late. All the assistance and trouble-shooting you need is in the newer program's built-in Help. That map may be ok in MS if you want to try, but please post in proper sections after searching in future.
These posts to trash soon.
