garmin key parser
You must run it in cmd-line mode. (Start Menu->Accessories->Command Prompt).
(it is simply a program to check gmapsupp.unl keys to make sure they are valid )
Then you must navigate to the folder the parser is located in, then type:
garminkey_parser <generated key>
garminkey_parser if the name is still garminkey_parser.exe and the <generated key> should be whatever key you got from the keygen (without the <>).
You can put unlock code as an input and get FID, PID and gps ID
