Just got back from testing my Garmin 750 after loading the POI Traffic Cam locations. Took about 10 minutes to set up and load about 16,000 locations. It gives an audable alarm at about .4 mile before and a pop-up gives desription (Red light or Speed Cam) and speed limit for area. Hit the 4 that I mostly go thru here in Tucson, all worked great, plenty of notice. Audio kind of like elevator bong sound, gets your attention good. Phoenix will be a lot more pleasant trip in the future.
