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.

The same thing is happening to me.

I do not think it matter as long as I have traffic now.

It may not be a big deal in not having Total traffic installed. TTN has restrictions, depending on the coverage. In my neck of the woods, TTN only gets info M-F, but not on weekends. I have Navteq as well and I've tried everything under the sun to remove TTN cuz Navteq traffic is better (for me) but I am now stuck with TTN as it gas a stronger signal. Remember, once the code is entered, you cant remove it. I have the 750 and I havent checked to see if there is a new traffic firmware update but if there is, I wont updated or maybe I will, if it kills TTN.

Does anyone know if there is a way to get the traffic update in Singapore with the GTM 25 and Nuvi 255 in Singapore? It seems to only work with the 1xxx series that are local units.

For those having a problem with TTN, you need to enter both codes (USA and Canada)...
