It Works....Trust Me!!!
This unit is always on when my truck is started. I travel 100,000 (+) miles a year, both city, rural, and highway. Yes is does go off at times,usually on a newer model SUV, may be from their back up alarms im guessing, but a different alarm chip is the signal. But it ALWAYS is on spot when I come up on the unwanted. Learn the chirps, and you will know whats false and whats real.
