Thread: Using TMC in Garmin nuvi for free

When did you buy the 765?

Unfortunately there is not a GCD file on the unit. I only just got the unit and so it came with this firmware already on it.

When I go into the diag menu by entering via holding the speedometer icon, the unit lists various subscriptions (although some are called "Not Named", the ones I tried to remove using VendID 0 do not have names there so these could be some of those, presumably along with ones that successfully added but never showed up in the subscription list in the Traffic menu).

Looks like I have to buy a new TMC then as there seems to be no way to remove these subscriptions...
