Thread: Garmin Bluechart G2 Vision unlocking

to unlock an unlocked IMG
rename the map gmapsupp.img and unlock with jetmouse keygen creating the unl file with notepad
[Only registered and activated users can see links. ]

on jetmouse keygen v1.5 put either the 10 digit gps unit id number (will be unlocked only in your gps)or the sd serial # (it will be unlocked in any gps you put the sd card
under-select map product --on the bottom ---custom map set---add the maps FID# also called mapid #

click generate a few times on the bottom-all those numbers will unlock the map--copy that 25 digit number into the gmapsupp.unl file --- don't add a enter --just 25 digits on the first line ----
on a sd card create a garmin directory--in that directory copy your gmapsupp.unl file (unlock file) and the gmapsupp.img (g2 map)
When you save the .UNL file in Notepad, be sure you set the "Save as type" to "All Files", not "Text Documents".

Hey Catymag,

YOU ROCK !!!
thanks to your advice, I just unlocked my map concerning Andriatic Sea & Ionian Sea (map ID= 234)
I just bought a brand new Garmin 421s chartplotter.
Thanks to you, I don't need to BUY the map. I just downloaded & unlocked.

THANKS AGAIN MAN. !!!!!!!
