Hey Dude,

Look at my post above yours where i outline step by step what i did. This is it step by step. The only error i made was thinink the number on the bottom of my garmin was my UNIT ID , its not you need to go Settings > System > About to get your UNIT ID.

After youve generated the correct key you need to do:

3. I then used the "garmin_unl creator.exe" to create the "gmapsupp.unl" from my unlock code and then pasted this file also to the root folder where the new .img is on my garmin device.

Once i generated the correct file it worked !!!!
