3 Installing a rear view camera in a R172 SLK Introduction This guide has been authored and compiled by members of the SLKWorld.com forum. Some words and pictures have been borrowed (with kind permission) from some professional installation guides where steps are most common. Dsr207 (Mike) - I have been doing my own custom and sometimes challenging install for a while now. Not much info available for R172 rear cam installs. I figured I would put some info and photo gathered from the web and my own installations. Hopefully others will have some input and share their own experience. Etyu (Eddy) - Added easy rear speaker removal instructions from his SmartTOP installation. MrPix (Paul) - I started putting all the information together for my own use during a Rear Camera install on my R172 and thought it would be great to share. My contribution is minimal as all I did was put it all together, gain permission from image owners then prepare the final compilation and publication of this document. Make sure your headunit is equipped with rear cam input If yes, you will only need the camera, if no, other hardware will be needed. The easy way to find out the answer is by shifting to reverse and see if your monitor goes black with a message "please check your entire surroundings". If you get that screen, you are set. If nothing happens, you might still be able to turn that option on through the "engineering menu". Going to that menu is easy. Just follow the simple steps. 1. Start your car (HU stays on this way) turn your radio or any other input on. 2. On the key pad of the head unit, press and hold the phone hang up, the number symbol(#) and the number 1, hold all three buttons on at the same time for about 10 seconds. 3. A new menu should appear on the monitor. Now you have to go to the bottom of this menu (HW setting) by turning the comand knob, then press to enter. 4. A new menu should appear, again go down to the bottom (HU parameter) and press to enter. 5. Another menu appears, you will have to go page 3 of this menu. Scroll down to the bottom and push the comand knob in the down direction, this will take you to next page, do the same again, you should be on page 3 out of On the bottom if this page you should see (21 or 22) rear view camera. Scroll down to it and press in to enter. 7. Change to SRVC. 8. Press back button and turn the unit off. 9. Turn car off. If you miss a step, at any time, you can just turn the unit off and turn back on to start over. 10. When all done, open door and out. 11. Lock car and wait one minute.

4 12. Now unlock door and turn car back on put in reverse and if the steps were done correctly you should see the black screen with the warning. NOTE: While in the "engineering menu" you might be tempted to change some other settings, but unless you know what it is, stick to task. No harm is done by entering that menu. Camera needed Any rear view camera with composite video out will work, it just depends on the options, mounting location and methods. You will need a clean 12vdc source and ground to power the cam, and tapping the reverse light will be required to trigger the cam. Depending on what you buy, some come with a control unit, and some have the grid lines and some are wireless. Needing a clean power source (for a good install) meaning you will have to run wires to the front, makes the wireless cam pointless. Shop around for a good quality, low profile, wide angle cam, CMOS or CCD. Removing head unit I found some pictures, which does a better job on showing than my dark pictures...so I used some, with little editing, and kept the name of the company that posted the flash. 1. Begin inside the center console...i used a small flat head screw driver, with scotch tape on the tip, to prevent scratching S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 3

5 2....pry and pull up 3. Remove the 2 screws S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 4

6 4. Pry and lift up. raise and leave folded up 5. Remove the 4 screws, 2 short and 2 long S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 5

7 6. Start from the top, left or right, 7. and pull out gently until loose S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 6

8 8. Pull up on the sides until loose, the left side is a little harder. 9. Unplug, small plug and command plug, the idea here, is to lift the panel out and lay it to the side. no need to remove all plugs. Putting the stick in D will help to remove panel. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 7

9 10. Once HU screws are within reach, take all 4 screws out and slide the unit out, and look in the back of it 11. The rear view cam input is in the twin green plug S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 8

10 12. You will need a female RCA to Fakra adapter.. You can buy on ebay, or make it yourself. Run the cable in behind the unit, and drop it to the left side. That is it for the HU...You will be plugging the cam to the cable later. Trunk Wiring and Camera Install Most do the install to the right of license plate...requires drilling small holes under the trunk lip per cam instructions. Dsr207 did his in the middle of the trunk handle and MrPix did his on the right of the trunk handle and to the left of the license plate light. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 9

11 Running the camera wires 1. Take trunk panel off. Use a soft flat edge, I used a small flat head screw driver, with scotch tape on the end, remove the 2 plastic inserts. Remove the 2 pins. 2. Pop the small handle cover off to get to 2 screws. Remove the 2 screws, and the panel will pop off. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 10

12 3. Run cam wires with the other wires. Tapping reverse wire (if needed) Some cameras/systems require you to tap in to the reverse wire to trigger and some just need a steady 12v feed on it s own, so this section is optional depending on need. In most cases, tapping in to the reverse lamp feed will not give you a clean 12v like you get from the fuse box, the latter being the preferred method of getting 12v either from the front or the rear fuse box or like MrPix did by tapping into the wires behind the 12v socket at the front. 1. Pull the liner back behind brake light S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 11

13 2. Look for purple wire (in my case, that was the reverse wire) or use a volt meter, to find the wire (12vdc when reverse is engaged) 3...after tapping the reverse wire, I used a coat hanger to run my wires. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 12

14 4. If fitted remove the air guides with a coin (quarter turn counter-clockwise). 5. For the following steps you will need a Torx T-20 and a Torx T-30 key. Remove the bases of the air guides (3 Torx screws each) and set all the parts aside carefully to not scratch the plexi-glass surfaces. NOTE The parts for each side are not interchangeable, so keep the apart! S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 13

15 6. Loosen the center speaker cover carefully with a putty knife or soft plastic tool, then pull straight up. 7. Tilt the speaker cover forward and disconnect both plugs for speaker (1) and park assist (2) if present. Remove Torx screw (3) in the middle. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 14

16 8. The side speakers can be removed in much the same way as the center speaker cover, they are clipped in with 6 clips all together. 9. Release 2 clips on the top and 2 clips on each side. The clips are shallow, so use a small trim remove wedge tool to free them and then unplug the speaker wires. 10. You can then tape the speakers to the seat belts to avoid damage. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 15

17 11. Remove the two round carpet holders (1) and (2) by twisting counter-clockwise. Remove the pocket (3) by pulling it apart on top while gently pulling toward the front of the car and up. Remove the entire roll bar cover (4) by pulling straight up and place out of the way (NOTE picture shows the speakers still in place, but you will have already removed these. 12. Pull both carpet bars (1) straight up, then fold the entire middle section of the carpet down. These cars have L and R on the back for identification and are not inter-changeable. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 16

18 13. There is a path directly to the front, behind left hand seat. I just poked a stiff wire through from the boot run and out it popped in a convenient channel to the right of the yellow square! 14. Once wires are through, run behind carpet, all the way to the edge of the driver seat. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 17

19 Tapping in to the power 1. Remove panel by driver seat door, it pops up, no screws, start from the back. 2. Once removed, fold carpet back to expose the wires loom. 12V is red with purple, and ground is solid brown. Use a volt meter to make sure you found the right wires, tap into the power. Alternatively, you can tap in to the 12v socket underneath the head unit. S L K R172 R e a r V i e w C a m e r a I n s t a l l a t i o n v1.0 Page 18

20 3. Run your cam wire to the head unit, going behind the carpet. 4. If you have to remove the left side panel under the dash, it has one screw, behind a plastic tap...and then it pops out by pulling it in the direction of the door... Hope this helps!
