reverse camera installation questions

Hello,
I just completed my installation of a backup camera using the detailed installation guides provided on this forum. I'm having a couple of problems and some questions I'm hoping someone can help with.
1. After installing the camera, I'm getting a black and white display on the monitor. I know it is a color camera as I tested it before hooking up to the vehicle on a color monitor in my home. Any ideas why the display would be B&W? The navigation screen is in color, so I know the monitor does display color.
2. When I place the vehicle in reverse, I see the camera, but a large amount of the screen is lost to the top and bottom headers shown on the display. On the top is the message "Check your surroundings" which obscures the top of the image. On the bottom is the display with the words "Back" which covers the bottom of the display. With these two areas covering the camera display, there is not much left to see. Can these be turned off?
3. I was a bit confused when installing the Fakra to RCA cable converter which I purchased from Ebay. What i got looked exactly what was pictured in the installation guide. However, the connector was not directly compatible with what I had on the back of the camera. The existing plug had two connections (one was vacant) and was not really certain what I should do. In the end, I remove the plastic connector on the end of the Fakra cable I purchased and then just directly plugged in the metal connector into the second port on the back of the radio. Is this the correct action to take? The instructions were not clear on this point.
4. I found in several cases, it was much easier to take some off, but rather difficult to put it back together. For example, I had a very difficult time putting the roll bar cover back on again. Seemed like a special technique/trick was needed.
5. Interestingly, I could not figure out how to remove the connectors from the side and rear speakers. Seemed like they should have been the simplest. Ultimately, I did not disconnect them as instructed but had to be very careful keeping them in place. Any trick to removing these connectors?

thanks,

1&2 Sounds you like have the wrong signal (PAL/NTSC) selected. OEM has the car accepting NTSC only. Most of us haven't been able to change that to PAL permanently.
3 The actual double 90 degree angled green fakra is a bear to obtain. You are correct that it is easier to just insert the metal part of the wire. If it's very loose in the connector put a little duct tape on the back to prevent it from wiggle its way out.
4 Taken the roll back covers off was easy? You are a master DIY. Those covers are a bear to get off. Snapping them back in place was a breeze.
5 All MD plugs have a little hook to keep them closed. This hook needs to be pressed in before the plug can be disconnected. Not all plugs are designed the same way, but the mechanism is in place everywhere.

Here's a couple of pictures of what I see when I put the car in reverse on my screen. One with a flash that shows the boundary of the screen, another without a flash, but it is a little dark. As you can see, the top and bottom portions of the backup image are obscured by the overlays shown on the screen. The camera I used was something I purchased with built-in line reference. It is possible it is a PAL based camera, but I didn't think so. I tested it on my TV which I assume is a NTSC based tv since I live in the US. But, maybe it is compatible with both types of signals. Is there a mode to try setting the monitor to utilize a PAL based backup camera?

Your pictures don't show anything out of the ordinary. Mine doesn't have the lower bar, but I have a 2012 model. Maybe things have changed.

In the engineering menu of your COMAND you can adjust the settings:
Press: "hangup button + # sign button + 1 button" simultaneously for 7 seconds
Option 7 (HW Settings)
Option 7 (HU parameters)
Option 22 (Rearview camera) should be 'SRVC' (Standard Rear View Camera)


7-7-10 (External Video Display)
3 Input settings
1 RVC gives the option PAL or NTSC

Don't adjust things you're not familiar with. It can brick your Comand!
