I have a K40-2000 radar detector on my G35. For some reason, it has started to do a constant beep whenever I turn it on. It beeps twice, then waits about 5-6 seconds, and beeps twice again, then repeats. Is this some sort of error code? I tried to contact K40, but they are not returning my emails. I think it's because I told them the unit came with my car when I bought it used. If that's the case, their customer service sucks! What's so hard about answering my 2 second question? Sorry, I'm on a tangent...anyone have any idea what the constant beeps mean? Thanks!
