I just got the V1 and see that since it has rear radar/laser detection, location is important. How high can you mount it? Is it OK to mount it so it over the level of the rear view mirror and to the driver or passenger side? At that level will rear detection be compromised or should it be mounted lower. I've read that only the rear right side of the unit (1 inch) needs to be exposed so mounting infront of the mirror more towards the passenger side would be best but could not be concealed by flipping down the visor.
