Even with it on, I've found it to work slow and crappy, my solution is to turn it on, then put 2 pieces of tape ove the sensor, which is on the front (hood facing) left of th mirror, i use a piece of painters tape covered with a piece of duct tape. piaters tape for easy future removal. Slightly dims the view during the day, which is an advantage.
Which brings me to a personal rant of mine, Technology for the sake of technology, that actually works worse then the simple manual stuff. Like the mirror. Give me a flip button mirror any day over this POS that blinds you for a second every f-ing time a car gets behind you, POS does not work, F-you, Chrysler. Or the stupid temperature adjust HVAC system, that alternately freezes you, then bakes you, were the lever in a 1972 Toyota truck worked infinitely better- I want heat, put it in the F-ing Red more. Nav system is also Crap, though not along these lines. My google phone can find stuff, the Nav can't find it's own azz. :boohoo:, i know, but c'mon, it's obvious this Sht doesn't work Chrysler. Go find some real engineers for this stuff. 392 works good though. : )
