I recently bought myself a new BMW X5. I had an Passport 50 in my previous BmW, but decided to buy a V1 for this vehicle. I hardwired it and used it for the first time over the weekend. I live in Southern California. The first time I used it, I got way too many false alarms. After doing some reading I saw how to customize the settings. I have all bands turned off except for Laser and Ka. I did notice that the range seems to be better on the V1. I picked up a couple of LEO's from a bit further distance than I would've in my X50. Overall I'm pleased.
