On my way to work this afternoon I went to use the cruise and it wouldn't work. The rangefinder indicator just blinks and beeps for a few seconds. I assumed that the rangefinder was just too dirty from road muck so I cleaned it off when I got to work but I still get the blinking/beeping indicator. It was -20F today (unusual even for Ottawa this time of year) so I'm hoping it's just the cold. Has anyone else had this problem before?
