Backup Camera for Car, Waterproof Rear-view License Plate Car Rear Reverse Parking Camera for C W203 CLK W209 SL R230 W211 R171 C219 S203 S211

Bought this for a 2009 Mercedes CLK 280 Sport Cabriolet.Fits perfectly (although the advertised item for my car would have had the curved lense upside down)The setup was easy, as I already had a camera in this position, but it got damaged.Image seems clearer than a the previous unit, and with this one I had the option to have the guide lines on or off by cutting/joining a cable.. I chose to have the lines off, as my android radio has the option also, and I figured if i used the radio setting, I could change the setting from inside the car without playing with wires.I get my power from my reversing lights, rather than have it powered all the time, and from the time I put the car in reverse, it's only a second before the camera pops up and is clear instantly. There's a 1 second delay for my radio to detect reverse also, so I wouldn't gain by having it turned on constantly.So no need to have it wired to a permanent live to have an instant image. (its on and ready before I have checked the view from the windows, so having it boot from reversing lights should prolong its life)Highly recommend this item, just check the options of lenses to make sure you get the correct fitting.My previous camera from a different supplier was ordered going by spec on advert, and when it arrived, the two curves on the clear lense were the wrong way round. The lense still fitted, but had to be rotated 180 degrees so the camera faced the right direction, making the lense look odd if you opened the boot lid and really looked at it.Check fitting image with your car, and not just by spec, as there are MANY variations and crossovers in car models.I am 100% satisfied with this purchase, and the quality of this camera.
