Thread: Using TMC in Garmin nuvi for free

I have a Garmin NAV system in my car, Kenwood DNX-9140. I needed to enable the traffic function and found a great solution in the "TMC in Garmin Nuvi" thead. This worked great on my Kenwood DNX-9140 running Garmin NAV and GTM-10. I enabled both the NAVTEQ and TTN traffic. I used Keygen 5 digit with the codes provided in post #119 for USA. The subscription key can be entered either upper or lower case into my DNX09140.

I have tried to add the Qld TMC (SUNA) however it doesn't work.

Does the GPS have to pick up the TMC service first? The provider is always "AUTO - Searching", so would that be the issue?

I know the frequency (97.3) and I receive the radio fine.

Nuvi 760 + GTM 21
