Last year I used it in parallel with 715,515 and bought 820 this time. Today was my first ride, is there a ghost? The sensor error is severe. There's no car, but it recognizes it as a vehicle. It seems to be too sensitive when recognizing bicycles or motorcycles. Is it because of the settings? Or is the removal defective?ㅜ My 1050 also had a lot of errors at first.ㅜ Me tooㅠ It seems like there are still a lot of updates needed. Ah, it even recognizes stopped vehicles. That's amazing...
