Garmin 3490 Is the best automobile GPS ever made for my purposes.
For full disclosure, I don't use the traffic function. It's awful, but I don't care, as I don't need it. If you're looking for traffic monitoring function, look at something else. As a navigation device, the 3490 is better than any other auto GPS machine I've used, including the ones that come with new cars. Any automobile GPS Garmin has made since discounting this product is inferior. No exception in my opinion.
