Giomen and Catymag, we generate (by Donpepe) parameters to the valid signature with your help, great! but the system is not yet identified traffic. When everything is working, I put the parameters here. thank

Nice one!

Another strange thing is that it shows a lot of traffic info from Rio, Porto Alegre, but a lot less from Sao Paulo (where i live).

In time: I believe this is caused by the FM GRID, which is US in my Nuvi. Originally Posted by rene.dare

I have a nuvi 765T that reverts the TTN subscription to "expired". I did try to input the code generated for the 4 digit (post #10) but it says "invalid code".
In the GTM service menu I have "Subscriptions TTN (US, Can) 0010 64/0 Navteq (US, Can) 1001 7/0".
The unit was bought second hand and it came with the expired TTN and software: GPS 2.90; GTM 5.50; DSP 2.40.
Idid try to delete the TTN subscription (with code "0" at "Vend ID) and that was accepted but changed nothing.
Does anybody have an ideea what is going on?
LE: I did replace the original traffic receiver with another one and it did pick up lifetime subscriptions for both.Last edited by Superduper67; 14th July 2011 at 11:27 PM.

Officially only GTM26 are compatible with the system in Brazil, but we are working for at least the GTM 25 and above work. These keys are provisional. They were deduced by logical approach, but has many limitations. For while they serve only as tasting. Once I have a stable solution post here.<br>

Sorry if this is a stupid question, but what is the difference with, say, GTM20 (which come with 765T)? Did the FM encoding change or something like that? Is there an URL with their specs? Originally Posted by angelozip

Contrary to official information from Garmin that only GTM26 and above would be compatible with Traffic in Brazil, we can find the correct parameters (post 227) and proved that other types of receptors, such as GTM25 and above, also work perfectly. Lower versions have not yet worked, but the next days we will have more certainty from numerous tests. The compatibility issues seem to be connected to the operating system of GTM20/21, who do not read correctly the parameters of the signature.
