Thanks for your replies that really clears things up - I knew I was reading too much into this. That does leave me two last questions:

Q1: Windows Explorer - I know I can't view image file with it but can I use to drop and drag the img files to my GPS unit thus avoiding all Garmin tools? Yes, gust drag and drop, no ganrmin tools required

Q2: With the .JCV file, I did see the JCV subdirectory and the name of the JCV file is different. Do I:

a) Copy in the new D3060070A.jcv file and leave the old one?
b) Copy in the new D3060070A.jcv file and delete the old one?
c) Delete the old one, copy in the new D3060070A.jcv file and rename to that of the old one?

A .jcv file matches a specific version of a map. You can delete any old ones. Never rename a .jcv or it will not work. The only time you might use more than one .jcv is if you have more than one map. In the case of multiple maps, the 755 knows (by unique filename "DxxxxxxA.jcv") which .jcv goes with which map.

- Thanks again -
One more thing... If you have multiple versions of a map installed, enable only one at a time. Otherwise, they will not work correctly. For example, if you have both "CNNA 2012.1" and "CNNA 2013.2" installed, select only one at a time because they cover overlapping geographical areas.
