Maybe if you write to Garmin and ask why is not Brazil traffic in nuvi 255W FW and if they can add it.

It may be that now, and only now, is it possible to claim for Garmin. That's because she only recently began selling a cable receiver separately of gps, the GTM35 already with signature installed (before Traffic original was available only to those who buy certain models of GPS). However, if the job is much more complex than the mere insertion of Navteq Br in the firmware, it is quite likely that Garmin responds that are not compatible, since xxx are out of line production at long time. Everything indicates that many parameters have to be entered, such as those contained in trafficprovider. The worst thing is that it would have to be done for the entire line of models 3 digits (xxx). In short, it seems very unlikely that Garmin meets to this request. Anyway, who bought a GTM 35 with official signature can try to claim with the Garmin, hope is the last that dies, and you are one of them .. lol. How about trying to enter the provider NAVTEQ Traffic (BR) in the firmware?

Can you also try with 31495, 13, 13,1

Despite of ok in infouc, has no parameter ltn Navteq Br and thus the parameters of signature, 11/a2/7/13 (11/00/7/13 in gtm26) not equal to the signal of RDS transmission (11/a2/7/14), so not tunes Traffic signal. The identification of the provider (Navteq Br) appear as Not Named, by the way, exactly the same thing that happens in Nuvis XXX, due to lack of the name in the firmware, as you pointed out earlier. In my case due to the loss of the relation with the parameters of trafficproviders.

Can you upload some picture from xxx model that we can see what abnormality is in developer menu in fm table?

I do not have any nuvi xxx available. I believe the rtsouza user or one that has a nuvi xxx can collaborate. Far as I remember, after installed signature in this nuvis, the provider appears as Not Named.

I think something is in this GTM type3 FW 3.10, becouse also 1 user with GTM35 have problem after update, and antenne stop working.

I'm putting this question in the appropriate topic [Only registered and activated users can see links. ]
