As I have for years, I use a 5" Garmin with lifetime maps and traffic. I buy them factory refurbished since they look new (probably are) and they have the same warranty as new ones. I had to send one in for a warranty repair and it went seamlessly. They run a little over $100 ($100-120) delivered. The maps are updated 4 times per year (every 3 months). My newest one alerts me to school zones well before I get to them. My other one (not counting the one on my motorcycle) has a traffic camera warning if I approach a red light or speed camera. I suspect the one with the traffic camera warning was actually refurbished and the first owner had chosen that option. I find them on E-Bay or Amazon.
