Thread: How to use GMapTool and cgpsmapper to split a Garmin "IMG"

Why would you need to change anything with the internal name of the .IMG map?

When you look at a list of maps that you have just renamed the .IMG map it show the name you give it.

Spoiler: Maps with the names I gave it

Even if I change the internal map name to the name I gave the .IMG file what does that being?

Unless you are trying to hide the real name of the .IMG file.
Then forget that you did the name change and no longer remember what map this really is......
