I have one Valentine one which I take with me and use on 3 bikes/2 cars so I have a mount on each vehicle.

on the X5 I mount above the mirror as pictured above.

mine has X and K band disabled, I only detect Ka and lidar. this depends on your location but it cuts out about 90% of false alarms.

the arrows is the best feature. you can determine location the radar sooner and get back up to speed. half the time it's on a patrol car on the other side of the freeway.
