Thread: Using TMC in Garmin nuvi for free

Jetmouse has intentionally set Expiry period to Never, which is no good for my plans. gk_mod seems to offer solution for this problem. Right? Thanks!

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
---------------------------------------------

There is just one traffic service in Bulgaria and it is free. Premimum traffic is just new name of old traffic service. I'm not aware of Garmin future plans about the traffic in Bulgaria, but so far no official statements about changes.
The procedure how to activate it is described in Garmin Bulgaria web page and it is quite simple: use the link from first post of catymag on previous page -> add to cart -> checkout -> user name & pass for myGarmin -> activate now button -> again activate now button on next page -> you should select your model -> enter your unit trafficID (how to find it /tools-settings-traffic-(subscriptions)-add/) and enter it in the field -> you will get the code. That's it.
It is reported that traffic in Bulgaria works well with all nuvi units with traffic receivers incl. old one. Unfortunatelly it's accuracy is still not good. Do not expect miracles from it.
