Thread: Using TMC in Garmin nuvi for free

As I mentioned in my previous post, the TMC Receiver is connected. I get no receiver ID. When I try to ADD a subscription it tells me to go to the garmin website and provide the unit id number being displayed. The only number that is displayed is my Nuvi ID but no traffic receiver ID number. Again, the GMT 20 is connected. Both lights on the GMT 20 are lit. So I don't know what to try next. After I click NEXT on the Nuvi it prompts me for the unlock code given to me by Garmin. Again, there is never Receiver ID displayed.

Register The GMT20 at the MyGarmin with its serial number, once registered you'll get the Receiver ID from your units summary.
