I second that! I have an even older nuvi 370 with the GTM12!
With the GTM12 in, it complains about no valid signal.
I can add a subscription but need to know what are the values required.

tom, where did you find the above info?
I hopeto look through a 1460/1350 or even 1250 if they are from a working GPS...

From Garmin, called TrafficProvider.xml
Singapore is free traffic, no subscription values available

Does the 3760T TMC work in Singapore, since it is US unit? Also I can't seems to get the JV or LA to work in Singapore. I guess the 3790T suffers the same fate as well.

I tried keygen to add TTN (both us and canada) to my recently bought 265wt with GTM25. It works even though I haven't seen the action on the road. Right now I can receive traffic info around where I live.

bucho96 · 29th September 2010, 01:37 AM

I have a Nuvi 660 and the keys for Canada and US are accepted into the Garmin, but it still says expired. I live in a decent area where I get traffic updates all the time anyone else having this problem and any solution?

Has anyone been able to verify using the USA and Canada keys on the Nuvi 760 works?

**Daedelos** · 6th October 2010, 03:04 PM

I'm looking a the keys in TrafficProvider.xml on my Western Europe 1340T using InfoUC v2.30. It gives the correct Family ID etc but the Unit ID looks wrong & doesn't agree with the GTM25's Unit ID. Is this correct?

TrafficProvider.xml also seems to have valid Australia and US keys but the 1340 doesn't list them. Do they only appear on the unit when a signal is received? Strange as I get France/Belgium etc even though I'm in the UK so I thought I'd get Australia/US listed as well ...

I found TrafficProvider.xml in my loaner 1250.
Unfortunately, I cannot find TrafficProvider.xml in my nuvi 370.
The only xml file I can see is Device.xml

Anyway to get the values into a nuvi 370 or am I SOL?

I think you just go into Traffic Subscriptions on your unit and add the subscription with the key generated from the KeyGen based upon your unit id, FID, Pid, RgnID & VenID for the relevant traffic provider.
