*DIY Rear Camera install w/Pics - Centered Location
Vadar ... you wont happen to be stopping by Alaska anytime soon for any reason would you? lol im going to hawaii in January but i cant bring my car.

Would love for you to help me if i got this.
phranksmbz..... The closest I am to Alaska is watching ‘Deadliest Catch’ on the Discovery Channel!
But when you’re in Hawaii send me a PM and I’ll make sure you get to see the best places! To see & eat!
However after 2 months, it blew out my audio's fuses twice! And now my C350 doesn't have audio/nav/phone...
And TJ just told me to connect the (red+purple) wire to any ignition source, and not to the reverse because the module is already supplying power to the camera. So.....can you tell what's correct?

post back which fuses it was and ill get you stepped through a resolution.
… to me at least. The only physical connection to the Radio unit from the camera is the RCA cable. I also talked to TJ and he stated it was just a choice because the wiring harness is closer to the RCA output from the camer kit. MidCity wires theirs to the cigarette lighter (they do this all the time!). I chose to wire it to the rear for ease of installation, TJ also stated this was fine.You say, ‘the module is already supplying power to the camera…’ then we wouldn’t need to hook up the red wire just the trigger (purple)….. But we do have to hook up the RED wire.
After two (2) months your fuse blew out…. That sucks! But I would suspect your wires behind the head unit? Frayed or grounded? Is any of the VIM connections/wires pinched or grounding? Those would be more likely to me for blown fuses. I don’t believe the RCA cable has enough current or grounding ability to blow fuses IMHO.
Let us know in two (2) more months if you keep blowing fuses….. Ohh… BTW this post was more about the Mounting Location … You think you were able to describe accurately your conditions/systems without disassembly? I’m sure MidCity will help you figure this out. It looks more like installation error though… Good luck

Right now, I don't know exactly which fuse blew out. The first time when it blew out (yesterday morning) I took the car back to the dealer and they replaced the fuse for me. The whole day yesterday was fine and nothing happended, everything works just as normal. And today it happened again.
I was gonna checked the wiring behind the command unit, but since the whole thing is out of power, the monitor lid wouldn't open and it's blocking the top part of the center air vent, so I can't pop it out... So..I'm pretty much locked out from it until I get the dealership to replace the fuse for me next Tueday (10/21) ....
I will go check the fuses and let you guys know which one blew out...
thanks again..
I mounted the camera on the side and routed the RCA cable through the side of the seat and then tuck into the wiring rail in the floor. and it's a real ***** getting the wire through....lolz should've thought about routing the upwards

This is not correct even according to the Camera wiring diagram… Again good luck & hope it gets fixed soon!
yep, that was my original question. The camera's wire came with RED+PURPLE twisted together and BLACK alone. I called TJ once and he told me to put BLACK and PURPLE to GROUND and RED to POWER. The reason I even ask was because, on the camera's manual there is a fuse in the line between the RED(or purple, i forgot) and power source. The kit does come with any in-line fuse. That's where I got cofused mostly. So finally, I decided to just go with the RED/PURPLE to power and BLACK to GROUND. Everything worked just fine.... until now.
So today I spent nearly three hours trying to find a spot for the VIM and the plug unit to hide so I could get the damned thing back together, even though the camera feature doesn't work. Right now, the radio is only 1/4 inch short of seating but it's hitting something solid preventing any further movement.
A question for those who have made it work. Just how is the VIM positioned and where is the plug and which way is it pointing? I tried laying the VIM down with it's white plug to the left and the harness plug underneath and forward after trimming the bottom edge of the insulation but something is still blocking the last 1/4 inch.
Before I call and make a reservation for a room at the State Mental Hospital I'd like to give it another try but I need some new ideas.
Then the question why the screen does nothing when shifting into reverse can be addressed.
I believe this is now the hands down winner, Most Frustrating Car Project Ever, and I've had some doozies.

I hope these pics help.
I made sure the hooks were at the fullest upright position.
I made sure the power wire stayed on the side edge that it is plugged in. I also made sure there weren't any wires underneath the COMAND unit
I positioned the VIM + T Harness as shown. plug going into the VIM Module is on the left side.

In my first pic, the arrows are jetting out from the "hooks." Sorry, can't describe it any better. Just make sure they are in the up position when you reseat your COMAND. Otherwise it won't seat the last 1/4 inch.
And yes, as mentioned in a previous thread, your T-Harness is your rate limiting step. Nothing else really stops the COMAND from reseating apart from the stupid T-Harness.

So, the installation is complete and the next question is, why doesn't it work?
I think I'll stop in and talk to my MB Service Manager tomorrow and pick his brain a bit in re: why no screen change. I'd also like to find a virgin W204 and slip in to turn it's rearview camera option on since turning it off is just as easy. This would prove something, perhaps.
More to follow.
But alas... not the time to rejoice yet as I have a feeling the COMAND unit will be coming out again in the near future. So long as you don't touch the T Harness when COMAND is removed now, you should have no more problems with reseating it.
