I tried on my Nuvi 1450T and it seems to work. However, sometimes the GPS device gets tuned on the 96,1 MHz frequency which is Maplink and not Navteq.
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).
does it have one for Brazil?Provider Navteq (Br)
Area: Sao Paulo, Rio de Janeiro, Belo Horizonte
2823, 0, 0, 1
2823, 14, 14, 1
2823, 15, 15, 1
this does not work with the 765T gtm21
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>

New parameters for TMC Brazil NAVTEQ Traffic (BR) (FID now 5 digits)
These work better than the old ones. The new parameters are:
added in first post
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.

Newbie here with a question after reading this thead and trying multiple times to enable traffic.
I have a kenwood DNX 5140 with a GTM-10 attached. The basis subscription has run out and I am trying to enable one from here. I have used JetMouse 1.5 to create a key and It still does not work. can anyone point me to a good guide?
Depending on the country, the parameters for the keygen does not generate valid signature for GTMs below the 25 series, such as codes of Brazil, which means that GTMs 10.12, 20.21 .. are not compatible ..
