Watching DVD's with car moving!
Start car put in neutral, let coast - video will shut off as soon as wheels start to move.
shut car off, leave key in the on position and do the same thing, let coast - video will NOT shut off.
This tells me there is a way around it without any adapters.
this also tells me there is a power source (acc) to some module or something that tell the head unit when the wheels are in motion but, only when the car is started. has nothing to do with parking brake or being in park.
Kill the acc power to this and all should be good.
As soon as weather gets better where i live I'm going to check it out.
Will keep you posted

it wont work; unless you plan to pull the gps signal from the back of your radio as well. the radio uses the wheel speed sensors + gps info to determine if the vehicle is moving and if it is the video goes out.
also if you cut power to the wheel speed sensors the car will spit out an unimaginable amount of errors...

do you have to do a series of key commands before you can watch it? Or do you just choose the dvd player as you drive? Also, if you get multimedia, does it come with a TV tuner? It says it unlocks TV, but didn't know if the w204 comes with the tv tuner.
I agree with you about DVD Audio... They made a big deal about it when they first came out; I remember seeing the display at tower records with all ten DVD Audio releases. I think that the ipod revolution has simply made the idea of HD audio redundant at this point.
Is this what you did with your car? So you don't need to buy any of those adapters for VIM but gets the backup camera to work on your MM system?
I was wondering if you can also post a photo where your backup camera was installed in the rear bumper.
Thanks
At least on the w203 models with CD based Nav. It's an option deep in the star Diagnostics program. It's set to "OFF" in the factory settings, just need to check in "ON" if it's available. I'll ask one of the techs I know to see if it's possible on the w204.
Lots of w203 owners have done this mod, I have it on my car with TV-tuner and DVD player, also have one other video source available for back-up camera, etc...
Has to be possible!

Also if possible what particular brand of camera did you use and is it good in terms of coverage.
A screen shot from your MM would be great.
I would also like to know if your MM automatically pops up during reverse?
If it pops up does it go back to hiding once you disengage reverse?
It would be really great if this can just be done via programing.

As a side note I saw something very interesting yesterday as well: The guys who put in my camera were able to program the camera on in another c class using just a laptop and an adapter cable.
EDIT: Checked the radio: backup cam only works if the radio is on and screen is up.

Love the back-up cam!!!
I'm adding that to mine soon too.
Also, do we need to run the video signal wires from the camera all the way to the radio or is there a connector in the trunk somewhere?
Thanks for all the info & pics you've provided us!

Well one thing I hope can be done to your existing set up is for it to work by automatically popping up the screen during reverse like in the movie national treasures.
