I used:

Code:

Nuvi 760 with GTM 20 the code works for 60 seconds and then reverts back to expired.

I tried several different codes but no luck..

FYI about a month ago my Garmin give me a notice of OTA firmware upgrade for traffic receiver and please wait, it completed and I thought nothing of it. Do you think they defeated the keygen. Does the GTM check in with the mothership and once it sees the code is key generated it sends the expired command. I notice a lot of flashing lights after I hit done then it says lifetime subscription 60 seconds later reverts back right before my eyes.

Update: I got the NAVTEQ (US, CAN): 28935, 0, 0, 1 to work. but Total Traffic Network is still listed and is listed as expired.
