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

Hmmm...could be a issue with the localization...therefore the mod (preinstalled settings)...For example the FM TMC signals in EU are even but in US/CA odd. This is automatically set in the localization. I might be totally off the way of course....I think first we need more information from your nuvi before diagnosticing the problem, and better open a separate topic, from the service menus. Please, make screen shots from the "mileage service menus" after the nuvi had acquire satelite signals in your car. In specific the service menus for the TMC and GTM. I don't know how exactly are they named in this nuvis. Also you can make a screen shot from the "battery service menu". Think the first page is enough.
