Thread: Lock a img-file

Use the locked IMG file in combination with an UNL file which contains the unlock code for that particular one unit. Create the unlock code with [Only registered and activated users can see links. ]

Instructions how to use in post #2.

I can't get this working. I've copied the original map-file, GMAPSUPP.img, to the memorycard with GMAPSUPP.unl.
In the GMAPSUPP.unl I paste the unlockcode I generated from Jetmouse Keygen.
When I boot up the GPS, I get the message: "The map can not be verified"

This is a Garmin Astro 320, and the mapid is 4548.
Can someone please help me? :-)
