When Garmin introduced lifetime traffic in 2008, it came bundled with their units but was ad-supported. You can see an example in the screenshot below. Personally, I found the ads low-key, but they certainly annoyed lots of folks.
Well get this — I was testing the nuvi 3597LMTHD for traffic coverage the other day, when I thought, oh yeah, I need to mention in the review that HD traffic is ad-free. Well that triggered an epiphany, because my next thought was, gee, I don’t recall seeing any ads when I tested the nuvi 2597LMT or 2797LMT. So I dashed off an email to Garmin asking about this and my contact there replied, “the 2013 units don’t use any ad-supported traffic.”
So there you go. All nuvi 2013 LMT or LT models are ad-free, even the Advanced series. I guess I’ll need to update my post on how to get ad-free traffic on your nuvi.
