@babj615,

Lets say you do 100 maps locked to a GPS unit.

Then the GPS Unit stops works for some reason.

Now you have to unlock these maps so you can use it on another GPS Unit.

The same holds true if you setup a GPS unit for someone else.

The person will just unlock the maps and use it where they want to.

When you look at all the tools out there to unlock.

Or am I not understanding what you want to do???
