Thread: Using TMC in Garmin nuvi for free

I did this with my nuvi 760 and it display that my signute is Lifetime Subscription, but only for a few minutes, then it returns showing expired subscription, this is for the TTN (US).

The Navteq (US) works fine, is OK.

I use the GTM20 traffic receiver attached to the Nuvi 760, my software version is the last v4.9 .

Same problem here....Why it is doing this???

I had the exact same thing happen to my nuvi 760 when I entered the key code for the Total Traffic Network. The subscription went from Lifetime to Expired in minutes. I entered the key code for the Navteq and it shows a Lifetime Subscription. It also shows the Total Traffic Network as Expired. I am using the GTM 20 traffic receiver that came with the nivi 760. The firmware is version 4.90 and the maps are 2011.20.
