Thread: Using TMC in Garmin nuvi for free

I've got GMT 25, 26 & 35 and they're also like that and all came with L(M)T units. I'm sure that's the way every GMT has been, none have ever been locked to a specific device even when boxed with Lifetime subscription units.

Thankx

Thanks Loly, I was referring to the ones we were talking about (25, 26, 35 & 36). I should have said 'I'm sure that's the way any one of those GMTs has been, none have ever been locked to a specific device even when boxed with Lifetime subscription units. Thanks for the clarification.

I notice dasilvarsa finds that his 36 works with other traffic capable units that he has tried it with. I know he has a 1300 for sure, could the restriction on GMT 36 be regional? I have never owned or used a 36 here in AU.

Yes, GTM 25, 26 & 35 all work for me on all traffic nuvis also, tried on 265W, 1300, 1350, 1390, 1450, 2350, 2455, 3790/3490. Maybe dasivarsa can report again on using his 36 with other nuvis that support traffic, and which ones specifically.

GTM36 works on nuvi 1300 and 3490, The provider here is Altech Netstar.

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). Who wants to read a little about the subject, see the topic [Only registered and activated users can see links. ] post 27 and others.
