I have mine mounted above the rear view mirror, hardwired into the overhead console.. very stealth.. There's a project if I'm not mistaken on how to hardwire it.... My detector has 360 capability and this seemed like the best place for it to see out of the whole cab of the truck. Line of sight clears the headrests and all..
I just stick mine to the bottom center of the windshield, suction cups on the glass and the bottom rests on the dash. I do not leave it in all the time because I'm afraid of it getting stolen. I just put it up when I need it.
