How to patch unlock any Garmin mapset

Require:
1. Gmaptool (gmt.exe) put in c:
2. GarminUnlocker.exe put in c:

Solution:
1. Split mapset into minor maps.
2. Patch unlock every minor maps.
3. Combine minor maps back to mapset (gmapsupp.img).
You can create new combined mapset name.
You can use new FID,PID for combined mapset.


Batch Commands:

# Copy your mapsets as path below.
c:\Garmin\TSM-TH\gmapsupp.img


# Make sub folder.
md c:\Garmin\TSM-TH\s


# Split mapset into minor maps.
gmt.exe -s -o c:\Garmin\TSM-TH\s c:\Garmin\TSM-TH\gmapsupp.img


# Delete unuse files.
del /q c:\Garmin\TSM-TH\s\*.mps c:\Garmin\TSM-TH\s\*.unl


# Patch unlock every minor maps.
GarminUnlocker.exe imgset c:\Garmin\TSM-TH\s


# Combine minor maps back to mapset (gmapsupp.img) with new name and new FID,PID.
gmt.exe -j -o c:\Garmin\TSM-TH\gmapsupp.img -m "Europe 2010.20 Unlocked" -f 555,1 c:\Garmin\TSM-TH\s\*.*


# See detail of new mapset (gmapsupp.img).
gmt.exe -iv c:\Garmin\TSM-TH\gmapsupp.img


Notes:
1. New FID value will not affect all inside minor maps. These mean you can choose any mapset name and any FID.
2. If your mapset have the Type (.typ) file or Transparent POI map (*.img), you have to use the real FID.
Gmaptool can't know the FID inside the Type (.typ) file and Transparent POI maps (.img).
You have to use -f option with a valid number. So we can't fake the FID.
