I seem to have an intermittant problem when coming to a halt. Sometimes the parkatronic system activates with the two red bars illuminated and it beeps. I don't think its always happening to me with a car infront as I stop, sometimes at a junction it happens. Besides, even when there is a car infront, I'm no-where near close enough to warrant it beeping. I have cleaned the sensors, and the system does work normally. When using it to park, it does seem to get a little confused sometimes, ie when reversing, sometime its just doesn't "see" anything, but shifting out and back into reverse cures it. Anyone else found these systems less than 100% reliable?
