Thread: GTM36 and GTM26 problem with TMC on nuvi series 2xxx and 3xxx

The intention is to understand why your 3490 with GTM36 not work. Moreover, would be great to know of some 34xx, 24x5, 25x5, 35xx with GTM36 or 26 (JetMouse signature) that works, in both would be important to observe the screenshots of the "GTM Status" and "GTM FM Table".
The GTM 36 and 26 with signature JetMouse work with all Nuvis 1xxx series in my country. The nuvis xxx don't work with gtm25/35/26/36 here (japanese fw for 1360 works only with gtm25 here).
In all cases that I observed, personally and with users forums of here, Jetmouse signature not worked in 24x5, 25x5, 3400 and 3500 with GTM 26 and 36, independent of alterations in region 140. A possible cause may be the hypothesis raised in my previous posts (the need of ecc in signature and TMC radio that transmits 4 parameters, including ecc) . I not only tested the relation of the change in region 140 of the new firmwares with the functioning of Traffic official signature in GTM36 and 26 of nuvi 3490. Apropos, the Traffic signature in your GTM36 in 3490 (pure or 3790?) was the official or of the Jetmouse?
