I used the Garmin Varian rear radar detector on a 40 mile ride this morning. It worked flawlessly. It let me know when no cars were approaching (green light) and let me know when vehicles were approaching (amber light) As soon as a vehicle was about 150 yds away a small white led ran up a scale of about 10 leds until the vehicle was right off my left rear. If vehicles were coming faster than posted speed limits a red led lit up. Bottom line amber is look back, red is forget it. 4 of the red rear leds flash until a vehicle is detected then 4 more flash and intensify as the vehicle gets closer. I feel a little safer and do not constantly look back. Pretty cool.
