Alright just a few days ago I was at the airport. My x50 goes off with a laser warning, no cop around? Then K band, again no cop? I was just assuming it was all the radars and crap they have at the airports. Well while I was waiting for my parents to arrive outside, my radar goes into self cal. It fails and says service required. I unplugged for a minute and turned it back on. Shows K warning and went back to service required. Did this a couple more times. Finally I turned off the radar from the volume switch thing. I waiting about 5 minutes. Turned it back on and it was fine. Same night Im driving home and there was a cop, Ka goes off but it was too late. It seemed like instant on but it wasnt because there were many cars passing by. It went off only like 200 feet away. Luckily I was doing the limit because I was afraid my radar wasnt working. Next day I reset the radar and I drive around to grocery stores to see if its working properly. It seemed ok but I think Im being paranoid. Do I have to send it in for service? I heard alot of horror stories from people sending their rds in for service to Belscort.
