I have the concealed display that 02V8Sport has, but mine is mounted in the upper left corner of the windshield, right where 04SCTLS has his actual V1 mounted. 3m double faced tape on the backside of the concealed display allows me to attach it to the uppermost corner of the windshield, with the actual arrows/display facing in a more downward manner towards my line of vision vs the slightly upward manner of the V1 itself shown in the pics above.
My actual V1 is mounted via velcro on my rear deck, slightly ahead of and to the side of my 3rd brake light cover. The V1 controls face the trunk, the V1 antenna faces forward aimed directly out the windshield with a clear path between the front seats. I drilled a small hole into the deck, under the V1, to allow the RJ-11 cord to go down into the trunk, under the rear seat, and along the drivers side door channel/under the sill plates. The RJ11 then connects to the Valentine power connection underneath the drivers kick panel, where I found a constant hot somewhere under there. (The hot goes out after about 5 minutes of key removal though) I mounted a power button for the V1 in the blank space just below the fuel filler door/trunk release button.
To top it all off, I purchased a spare 3rd brake light cover and have it sitting on top of the V1, open end facing forward, closed end facing the trunk. With my tinted windows, you cant see a thing. From inside the car, anyone looking at the rear deck has no clue whats there. With the 3 plastic seatbelt anchor covers on the deck, along with the factory 3rd brake light/cover, the additional OEM cover fits right in.
Yes, my radar and even laser coverage(laser goes off every time Im at a light behind a modern SUV with that LED 3rd brake light) is fine. Radar penetrates the plastic 3rd brake light cover, so yes, I have plenty of side and rear radar coverage. No REAR laser coverage, but I've never heard of a cop shooting radar at your backsside.
So it's in effect, a very stealth but easy install. The stealth is good for anti theft purposes and when I cross the Potomac over into the lovely Commonwealth of VA. The only state in the US were detectors are illegal for cars.
