I had mine switch on by itself too. I suspect it might have happened with the 2.90 update perhaps? Not totally sure on that. But yes, Garmin has a strange way of thinking when it comes to how they advertise 'Features'. Like Red Light & Speed Cameras. Now they are saying that 'Feature' is really just a trial, and after that, you have to buy a subscription. So the Feature is, the ability to lock you into a subscription for life, lol. Same with Traffic, that used to be totally free internally with the antenna, but now is being sourced via the phone, and your data. With the 660 the only thing linking the phone offered was the ability to place or accept calls on the GPS. Now, you have to tether the phone to achieve a good number of the features they claim, that are no longer internal, but slide past the part about the hijacking of your cell data. Thank God I have a Cell Data blocker as just messing around with Explore that I installed on the phone with Drive, I had no clue that the app will quickly burn through many GB if you mess with the maps away from WIFI. Between that and all the bugs, I'm not a real happy camper right now. The only saving grace is you can actually see the display now.
