Thread: Using TMC in Garmin nuvi for free

As the relations between GTMs receivers, gps models (and firmware) and local TMC signals are complicated, no? We realize that these 3 factors are the main determinants involving the Traffic works in one location and not in another, even with the same hardware. However, it is important to remember of another element which recently became also crucial for function Traffic: the type of signature. With original Garmin signature installed in receivers GTM25 and higher, the traffic works with all models of GPS, 1xxx and above. The recent problems happen with the receivers 26 and GTM 36 with signature Jetmouse. These receptors do not work with this signature with the Garmin 2012 GPS with the new firmware (24x5, 25x5, 34xx, 35xx), but work perfectly with those using the previous operating system (1xxx, 37xx and others).
