About the Crux CMB-18S

Custom-fit for your Sprinter

Make backing up in your Sprinter van easier with Crux's CMB-18S rear-view camera. The camera is housed in a third brake light assembly that replaces the factory assembly without having to drill or modify the van's exterior body panels. The assembly is completely functional as a brake light, and adds a custom-looking camera mount. Crux gives you a 32-foot video cable to cover the distance from the back of your van to the aftermarket video display in your dash. Once installed, you'll see a generous, well-lit picture of what's behind you on your radio's display, with a 170-degree wide view and excellent visibility for night driving.

Product Research


Mercedes Benz Sprinter Van Camera: The Crux CMB-18S Mercedes Benz Sprinter Van Camera is specifically designed for 2007-2017 Mercedes Benz Sprinter vans with an aftermarket in-dash multimedia/navigation receiver or external video monitor installed. Your aftermarket receiver with video monitor or external video monitor must feature a composite video camera input. The CMB-18S will replace the 3rd brake light of your Mercedes Benz Sprint van. With the Crux CMB-18S Mercedes Benz rear-view camera installed, you'll be able to view what's behind you on your in-dash aftermarket receiver's video monitor when you put your vehicle in reverse.

Note: This rear-view camera is meant as a back-up aid only; never solely rely on the rear-view camera when backing-up. In addition to using the rear-view camera, always look behind you to make sure everything is clear when backing up your vehicle.

Image Sensor & Lens: The Crux CMB-18S Mercedes Benz Sprinter Van camera features a CCD image sensor that offers 480 lines of resolution (NTSC or PAL compatible). The bright f/1.2 lens has 170° (horizontal) x 90° (vertical) viewing angle. Eight infrared (IR) LEDs provide a minimum illumination of 0.0 Lux for excellent visibility at night. You can manually adjust the angle of the camera.

Park Assist Lines: The rear-view camera provides parking assist lines on the screen of your vehicle's in-dash aftermarket monitor. These parking lines are there to assist you when backing up into a parking space. There are two vertical lines which help you judge the left and right edges of the parking space and your vehicle. There are also 3 color-coded horizontal lines that are used to distinguish how close you are getting to the end of the parking spot - Green (Clear), Yellow (Getting Close), Red (Very Close).

Note: The park assist lines are turned on and active by default. If you prefer to turn off the park assist lines, you will need to cut the blue wire loop on the the attached power/signal cable of the rear-view camera.

Connections: The camera features an attached 6" power/signal cable which plugs into the included 32' extension cable. The 32' extension cable plugs into the included 18" composite video adapter cable which also features attached 3' power/ground wires. At the end of the video adapter cable is a male RCA composite video plug which connects to the composite, rear-view camera input of your aftermarket head unit or external monitor. The power (red) & ground (black) wires will need to be hardwired. 12V power can be obtained from your vehicle's reverse light circuit or from the reverse gear wire of your aftermarket stereo (if applicable). The ground will need to connected to your vehicle's metal chassis.

Waterproof Housing: The Crux CMB-18S Mercedes Benz Sprinter Van camera features an IP67 waterproof housing.

Customer Q&A

2 questions already asked

What are the unit's exact dimensions, best a technical CAD drawing? Is the mating surface flat, and does it attach by those the bolts visible at the lens corner?
[ BertW  Apr 19, 2021 ]
1 answer
Mine fit into the existing third brake light opening. The crux model didn't lay as flat on the body as the factory and used I some silicone to make it water tight. I don't have the exact dimensions of the opening.
[ JOHN  May 12, 2021 ]
What aftermarket display do you recommend to use with this unit?
[ Schmidty  Jun 11, 2019 ]
1 answer
You display that camera on a rear view mirror, dash or windshield mount monitor or a touchscreen aftermarket radio. It depends on your application which will work best. You might consider a rear view mirror replacement like this Boyo: or a more universal monitor like this Accele: If you questions about either of those options or want to look at radios you can connect with one of our friendly product advisors here:
