I've had mine....(the older A model) hooked up for about 4 years now with no problem and all of the sudden, it just seemed to stop working. I still reads, but like 30mph too low. And adjustments don't seem to get me anyhere. The only thing I did before it stopped working was disconnect and reconnect the battery. I know it's and electronic device and like everything else...falable. Has anyone else just had one "go bad"?

Have you contacted their tech support or looked in the FAQ section on their web site?????
