GPS Lodge has an in-depth review of the Garmin nuvi 755T and despite some initial apprehension regarding the effect of ads on its usability, it was found to be a more-than-fair tradeoff for free realtime traffic. And there was really nothing negative to say otherwise. Navigation was solid, advanced features like Lane Assist were effective and it was a definite recommendation for anyone looking at higher-end GPS units. So keep your eye on it when it hits shelves October 1, it might be worth the $500.
