I was in Las Cruces, NM the weekend before last and got a bit disoriented with my Tom Tom. I ended up getting off the right road and having to turn around to get back on it. When I approached a stop light up ahead I suddenly got an alarm on the C100 that I hadn't heard before. Sure enough...I was approaching a red light camera. I got plenty of warning and my wife and I were sure glad we had the C100 with us.
