I was driving up to Boston last night, and my radar detector would go off on k-false alerts every 30 seconds on Mass Pike. It would suddenly reach high numbers (8-9), then abruptly stop. I must have experienced this alert at least 50 times. Then, when I was visiting my gf at wellesley, the radar detector kept going on Ka alerts, with the same problem. However, the Ka false alerts happened every 10 seconds! For an hour I had to endure its constant alerting. I don't know what is wrong with the radar detector. I had it set to Pop Off, Ka MAXID, Filter 2.
Please help! I think my radar detector is going haywire! I don't like that it is being very unreliable.
BTW I did a factory hard reset 5 times and set the correct settings, but the problem did not go away!
UPDATE: The radar detector did go off K band because an Audi A4 passed me. I searched on forums that it may have to do with their Adaptive cruise control, lane assist change feature that used radar. But it still doesn't solve my Ka band false alerts!
