My navigation manual mentions that it can provide even better routes if Traffic Message Channel (TMC) information is available. How do I add inexpensive TMC to my navigation?

I appreciate your suggestions.

You would probably need to buy the official tmc receiver for your device, if one exists.

Question of sorts: You have to pay for TMC in the US - it's not free regardless of the device! IMHO, forget it. Traffic conditions change so fast here in the US.

Anyone know if TMC is free in Australia?

It is in the UK.

You could give it a try?

Right now I don't have SiriusXM subscription. If I opt for it (with traffic subscription); do you think it works?
