Using TMC in Garmin nuvi for free

ShadowDragonz · 12th October 2010, 01:52 AM

Thanks for posting this great information! For informational purposes I own a Garmin Nuvi 760 and the Navteq TMC confirmed works lifetime. Total Traffic Network (TTN) confirmed will expire within a minute even though key appears valid. I will continue to search around and find a way to get TTN to work and report back my findings. If anybody has a suggestion here I'll try it and get back to ASAP!

Edit: So far I have had no success... I currently have CN North America NT 2011.20 map installed even though it's technically not relevant. On another note, for more technical information, the GTM 20 firmware is up to date a 5.50 and my actual gps software version is 4.90 (May be outdated)

Can this .xml file be edited and saved or would that cause more problems?

Is there a way to make traffic to work in Sinagpore? I have nuvi 3790T with gtm 35, but I can't get any channel.

Switch to SG/MAL FW

Sorry, really missed it.
You can edit it, but which result do you expect?

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.

Like others, I can't get the TTN subscription to stick in my 750, but NAVTEQ works fine. I entered both the US and Canada TTN codes, and although I get a lifetime subscription briefly, it reverts back to "Expired" within minutes. One time I saw it change to "Expires 1/6/2009" first, then to "Expired" within a minute. Any ideas?
