Thread: Using TMC in Garmin nuvi for free

That would also be useful to generate keys for AD-Free NAVTEQ traffic. There used to be a MOD version for extending the expiration date for the old trial versions on TTN. The filename was "jmgkg13modTMCExp.exe". Unfortunately, you could only enter a code to control the expiration date (adds in week increments ) but the FID was hard coded to use 28992 regardless of which product was selected from the dropdown list.

Reverse Key Example of what it did:

---------------------------------------------
UNLOCK KEY : N954Y-5MA2T-EVQ5R-ZXVAH-PXVEY
---------------------------------------------
KEY IS VALID: YES

Unit ID : 1234567890
Family ID : 28992
Product ID : 0
Region ID : 0
Vendor ID : 1
Date expire : 26.06.2079 (week: 4095)
Product name: TMC:Total Traffic Network (USA) lifetime subscription
