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.

That's correct. I was referring to the premium subscription service through SmartPhonelink.

TTN or Clear Channel does not broadcast in HD so even if you can get the TTN to work on the latest Nuvi's I don't think it's worth the hassle....if you have an older device like I do that already has the TTN code. It's also too bad that you STILL can't force your Nuvi to select which traffic provider through the traffic receiver/antenna. Having said that, it's not really a big deal whether or not you have traffic since most radio stations where they transmit the traffic info normally do not broadcast traffic during weekends or after certain hours.
