I have that on my Navigator, and it's mostly decent. The one on my Audi is better, it recognizes school zones and even recognizes active school zones (if there's a flashing light, the 'school' will flash, too). Also very nice (but is dependent on the signals) is the "green light countdown" where the signal is broadcasting how long until a given direction is turning green.
