Well, if we are discussing alternatives to fixing the existing one, then I have a model that has both visual and audible output modes. It fits in the passenger's seat. If the speed is too high, then the left foot will press on the floorboard at the low alarm setpoint. If you should exceed the high alarm setpoint, the audible alarm will activate. The programmers used a hillbilly Tennessee accent for some reason. I have not found a way to deactivate it.
