I will warn you guys that want to go wireless that you should take a harder look at them. At the headset I will tell you that you will be happier with the wired setup. Yes it is a little bit of a bother to run but you will be happier in the end. I have had a wired and a wireless. The first was a wireless unit that I put on my truck. It lasted for several years before giving up the ghost. I replaced it with another wireless cause on my truck I didn't want to run the wiring, and I am lazy. I love it for what I use it for, backing up and hooking up my trailer. Don't have to get out of the truck to hook it up other than to drop it onto the ball hitch. Don't need it for anything else, cause I have plenty of mirrors for that. The problem with the wireless units is that they pickup errant signals from restaurants, banks and department stores as you drive by them. The screen is always powered and the camera is switched on when the backup linght is powered. The screen is hooked into an acc, powwer cell or cigarette lighter, always looking for a signal. My wife and I used to go out for coffee and doughnuts several times a week. Sitting in the parking lot of the doughnut store listening to the radio(acc. power) we would enjoy watching the cash register workers at a restaurant that was in the neighborhood. Good signal, clear as a bell. We would also pickup other businesses as we drove down the street. Because I mounted the screen low in the cab, it wasn't a distraction. On your dash it will be constantly flickering on and off.
OBTW. If you plan to have the camera for constant driving you will need to mount it higher than your tag. All you will see is the car bumper behind you and nothing else. If your camera is more than 90 degree viewing angle(most are 120-170) everything you see in the camera will be TINY until it is right up on you. Consider mounting it on the rear hatch just above the engine. If that gives you too distorted a view from the angle going through your plexi then you will have to mount it on the outside either on the hatch or on the spyder. You may need a bump to hide it. Those cameras are usually small units that come in little enclosed housings which aren't that bad. You have to play with how they are mounted to give you the best view.Last tip, get ccd units not cmos.
