I'm not sure what I did with my JBV1 app, but I set it to turn off the display on the V1- this worked fine. However, when I have signals, other than reading the frequency and then figuring out which band it is, nowhere on my JBV1 display does it state the band. Is there a way to make JBV1 show me the band when it gets an alert? Also, I know you are not supposed to do this, but I put up my V1g2 and V1g1 up at the same time today and drove around. The V1g2 out alerted the older version every time, very very slightly in K or X band, Ka totally went to the new version. My old one still worked well but had many more K falses from other cars. So even though I had to send mine back I would still take the new one first. No instant on hits so still not sure of that issue, but everything else I like the new detector better.
