Just got home today... My dad already hooked up my V1 to the 300C but unfortunately it's intermittently (once every minute or so) falsing to laser for inexplicable reasons. I've ruled out laser cruise control -- even when the car is parked on the driveway with no reflective surfaces ahead I get intermittent alerts, and the frequency does not change with ACC on vs off. I've also stepped outside and pointed the V1 directly into the ACC sensor without any falsing.
Could it be unstable voltage / electrical noise? Do I need a ferrite core / choke?
