Thread: Using TMC in Garmin nuvi for free

Here, "free" only two official models of Garmin, specific to this market and embedded with lifetime subscription. As in other countries nothing has to be done so that the FM Traffic works on these devices, I am aware. The problem is how to enable the service to thousands of other Nuvi with receiver, since the Garmin does not sell and do not frees the subscription. After webupdater, the file TrafficProvider.xml shows the field <providerName> NAVTEQ Traffic (BR) <pay> true </ pay> for Brazil, it is clear that the service will be paid to the other models. The problem is that Garmin does not say if and when it will sell the signature, which can take a long time, years perhaps, because their interest is to sell its new products and strengthen the local distribution network. We know that one way to get the parameters FID, PID, RgnID and VenID are through a number of valid signature with Infouc. So, this number would have to discover from of the two officials models sold by Garmin, but how to find this number if the signature is already embedded in the device? This is an issue. The other is how to find the parameters (FID, PID ...), independently of the number of valid signature, in which place to find (file or operating system) in the official or "unofficial" models? (with WebUpdate and Trafficprovider.xml updated in both). I hope to have been a little more clear now. Thanks
