Thread: How to patch unlock garmin img

Hope this works...
Tell me if I do something wrong.
1. Downloaded Garmin Bluechart G2 Vision VEU708L North Nrway
2. Copyed it to C:
3. Unrared garmin_unlock_script to c:
4. run the bat file... (like alautre it displayed the warning on the marine map)
5. copyed it to a sd card..... no other files than GMAPSUPP.IMG on card.
Will this work when I install the SD card in my 421S ???
can't try it until next weekend.
