Buying the Correct Detector
Step
1 Figure out your budget so that you will get a detector you can afford. There are many varieties of radar detectors with a lot of bells and whistles, with prices ranging from roughly $80 to more than $350.
2 Decide if you want to install the detector or whether you want a professional installer to do it. This will help determine what kind of store you buy the unit from. Specialty car audio shops have technicians on hand who can install the units for you. If you buy from a store like Kmart, you will probably have to install the unit yourself.
3 Consider brand-name devices. Leading manufacturers of radar detectors include Cobra, Uniden, Whistler and Bel-Tronics.
4 Choose a unit that can sense wideband. The unit should be able to pick up the entire Ka band as well as K, X and laser.
5 Note the unit's sensitivity. Manufacturers sometimes publish lab-test results. Look for at least 110 dB.
6 Think about getting a unit with memory. This will avoid the need to keep resetting the adjustments every time you start up.
7 Look carefully at the display. Make sure you can see it even in bright sunlight.
8 Select a unit that has an adjustable volume. Consider getting a unit with a "Mute" function. If there is a police car cruising behind you, you can silence the detector so it won't drive you batty
Things You’ll Need:
Radar Detectors
Cable Ties
Grommets
Multiuse Screws
Screwdriver Sets
Silicone
Variable-speed Drills
Wire Cutters
Preliminaries
Step
1 Read the instructions that come with the detector. Don't do anything until you fully understand the instructions.
2 Gather the following tools: drill, screws, wire cutter, silicone, grommets, screwdriver, wire ties and/or wire loom.
3 Open the radar detector's box and make sure you have everything you are supposed to have.
4 Inspect the inside and outside of your car for locations for the components of the detector. You want the receiver to go in a location that is easily viewed from the driver's seat. Make certain that there are no obstructions - this includes your arms when your hands are on the steering wheel. Common locations for the receiver are the ashtray position, hanging from under the dash, or on the sun visor.
5 Inspect the car to determine the best locations for the other components of the detector, which include sensors for the front and rear of the car. The instructions will give you some ideas. Again, make certain that there are no obstructions in any of the locations you choose. Remember, radar cannot penetrate metal and laser can't penetrate plastic.
The Installation
Step
1 Mount the components in the locations you have chosen. Use screws to mount the items securely to a metal surface. You may find that you will need brackets to mount the items securely.
2 Run wires from components located in the front of the car through the engine compartment to the firewall. Select a grommet already in place on the wall and thread the wires through it to the passenger compartment. Tie the wires neatly together or thread them through a plastic loom to protect them.
3 Route wires from components in the back of the vehicle through the car to the passenger compartment.
4 Mount the receiver and connect the wires from the components to the receiver.
5 Tap power from the fuse block and ground to a clean metal surface.
Hope this saves u a few tickets. Lots of very good radars can be bought on radarbusters.
Make sure u get one that doesnt bounce of signals to the cop radars and cannot be caught
