Well, I figure I'll do a comprehensive review of a part of my car right now to help you guys out if you are in the market for a radar detector.
The Valentine One is right on the top of the list, just above the Passport 8500. Consumer Reports rated the V1 higher for the last couple of years I believe, and there are a few features that sets the V1 apart from the Passport. The only one that I know for certain is the one I will mention in this review.
That one feature that the V1 has over the P8500 is that the V1 can locate radar/laser from behind. This can be helpful if a cop turns out from a side street or is coming up behind you on the highway.
Ok, details about the V1:
It's expensive, and I'm not going to lie. For $450, you get the detector. I know you can get ones for about $70, but when it comes to something this important that can potentially save you from higher insurance, suspended lisences, and points, why settle for something less? I opted to get the Concealed Display ($50) which you can mount anywhere in the car pretty much. I have mine mounted on the steering column in the center, directly to the right of my OEM boost gauge. It attaches with some 3M velcro, and hasn't moved yet. Other people have mounted theirs where the factory Clock location is, under that little area on top of the dashboard. The thing I like about the concealed display is that you dont have to look all the way to the top of your windsheild to see what's going on. Just glance down at your speedo and you can see it. It reads in a red glow, which is very nice, easy on the eyes at night.
The detector makes a couple of nice beeping and chirping sounds when you turn it on, or turn the car on (depending if you hardwired it, like I did). There are three modes you can put the detector in, All Bogeys, Logic, and logic (lower case and upper case L's). logic (lower case) is the preferred mode that I use, and noticed that most other people use. It doesn't flip out all the time, but it still catches every serious threat. There is a very nice volume control, a mute button (that doesn't acutally mute, it just tones it down a lot), and a simple display. It gets radar in all directions. Front, back, and both sides.
The display works as follows: When the detector goes off, it will start with a single beep, and this beep depends on what signal it is from (X, K, Ka, or Laser). The beeps vary with the distance from you and the target, the intensity of their signal, and if it is pointing at you, or close to you. Once you get closer, the beeping becomes more and more frequent until you are locked on, and it is a steady "Beeeeeeeeeeeeeeeeep" That can, however, get sort of annoying sometimes. It also tells you what direction the signal is coming in, how many there are, and the strenght of each signal. It can also track more than 1 radar at once, so you can avoid speed traps.
Easy to use
Easy to understand
Saved me about 7 times from cops. Totally justifies the cost, IMO.
One of, if not THE best on the market
Plug and play installation
High quality build
In the dark it is hard to see which red dot says which signal (X, K, Ka, or Laser) because only the dots light up, not the text. I dont have this problem anymore because I know the order of them.
The Beeping can be annoying sometimes
Picks up basically EVERYTHING. Motion Detectors, those flashing construction signs on the highway, Supermarket Automatic doors, Taillights of Chevy Trailblazers, and other things.
However, I have thanked this thing so many times. Definitly works. It goes off when I'm driving around a corner and up a hill, only to find a 1/2 mile later, a cop nestled in some woods I never would've even seen if I didn't have this baby. Definitly one of the best modifications you can do to your car.
Hope this helps
