My issue seems different from most of the comments on this thread. My first issue was that there were no solutions offered.
The issue starts while I am approaching an over or under path that crosses the Interstate on which I am riding. I get multiple tones and then a red banner that crosses the entire top of the display screen. The banner, and I paraphrase, "exceeding speed limit by seven MPH or by 1 MPH. I get the tone about once every two or three seconds and they continue until I drive out or the intersections area. The tones cut out most of the audio that I am listening too.
Oh, the red banner appear regardless of what my speed may be.
