I don't have the audio warning, but it shows my speed in red if I'm over and it shows the speed limit, which is great because you don't know what the speed limit is sometimes. Its one of my favorite things about the GPS. You ever notice how the speed limit changes right when you reach the sign? It's amazing that they do that, like they drove down the road and put it in the program, lol.I also like the 'Audio Warning' Setting when I exceed the posted speed limit by more then 2 MPH. Great 'in town' also ....
