I've owned my V1 for about 5 years now, but recently it has started acting up. I get sporadic, front arrow, full strength, X band alarms. The alarm strength isn't gradual, it just goes straight from zero to full strength. It used to happen randomly - like in the garage and on the road. I would turn it off and on, and sometimes that would fix it, but today it just wouldn't stop. When it isn't going full blast X band alarm, it functions properly - going off at the usual places that I knew had radar around. I've never programmed it or anything. I just leave it in L mode. Is this a known issue and should I send it in for repair?
