Execute the command Maps; Manage products maps, and see that indeed the state of map is “locked” but we’re interested is the installation location which we’ll take note: is needed. Go to PGFT and click on Unlock a TDB file, after which we can browse to find the TDB file in the path that we’ve noted before.
Garmin Map Installer Unlock Codes
For information only, How to Unlock Garmin maps.
- The unlock code (gmapprom.unl) is a file that contains unlock codes for all the maps that were downloaded to the Nuvi. It is a 25 digit code that is added to the unlock file each time a new map is installed.
- All this maps could be unlocked in MapSource up to version 6.15.7 using code generated with JetMouse keygen without any extra procedure, but if your MapSource is newer, you will have to install version 6.15.11 (6.16.1) and overwrite it with patched version.
First get your hands on the desired Garmin City Navigator Downloadable Update for your country/city (MapSource A).
In the compressed file should be the folders IMG, support and Windows plus a readme.txt.
You will need a version of Garmin MapSource 6.13.1 or older which does NOT support Unlocking via the internet (MapSource B).
This can be found in older version of the downloaded map update files (perhaps a 2007/2008 version).
Run the CN.msi installation file to install the old version of MapSource (B).
Run MapSource (B) and the UnlockWizard.
Now get your hands on Garmin Unlock Generator V1.5,
Enter your 10 digit Unit ID, and select map product <custom mapset>, enter the FID (MapID) of the newest Downloadable Update (the one you want to Unlock).
Click generate, copy the 25 digit map unlock code and paste this into the UnlockWizard.
At this stage you will have the older version of MapSource (B) with some old map.
