Thread: Using TMC in Garmin nuvi for free

The Garmin subscription service as already mentioned is based on your cellphone's internet/data connection. When travelling outside your own country roaming data plans are very expensive so that is not a viable option for many. For within your country, I think you're much better served by subscribing to free twitter traffic feeds and free web based traffic cams then paying for a subscription or traffic service from Garmin. I now won't be bothered trying to get TTN on my 3597.

That's not actually how the HD traffic info is delivered via the GTM60 HD Digital Traffic Receiver. I think that possibly you are confusing the GSM 'Live Traffic' service via the SmartPhoneLink in Apps on your 3597, with the HD Digital traffic via the HD radio (DAB+) receiver in the GTM60 for which there is no charge. The NA GTM60 also has an OEM Navteq FM TMC subscription on board as well. I've also added a TTN FM sub to my NA GTM60 but i haven't been back to the States to test it but i don't think it will as 1 error is now showing. The Suna FM sub added works in AU though as it also does with GTM26/36.
