Thread: Using TMC in Garmin nuvi for free

So, I dug out my old GTM-20 and read every post here, but, like others cannot get rid of the TTN entry no matter what I enter - Navteq works fine, but I preferred TTN - and like others here it shows active for a bit then goes expired - I assume there's another FID code in the receiver that is overriding the ones published here - and I see no way to easily determine what it may be.

At least Navteq traffic works - who am I to look a gift horse in the mouth?

Older posts mentioned issues with ads - one poster said he got no ads with his 750, but did on (I believe it was) a 765 - I saw no reply to his comment and for posterity, I figure that loose ends should be tied - there is no ad support in any of the XX0 Nuvis - they all ignore ads, plain and simple.
