In June I got caught on my bike in a torrential downpour which damaged my 8500. After everything dried off, it still picked up radar fine and was well loud enough for me, but with no display (blue). I didn't mind, since I couldn't look at the display when riding (earphones were adequate) and in the car, having it always dark is good in VA too. Anyway, yesterday it started giving me a quick double chirp about every 5 seconds and won't stop. Since I have no display, I can't see what kind of code or readout it's giving. Does this mean my RD is really dead now? Would it be cheaper to buy another or mail this one off to Escort for repair?
