Was the cable loom damaged?

Maybe thay have swapped green and blue colours?

Zoom into a part of the sea that should be blue. Is it?

Your new nav has the latest SW version 3-1/63, what did you have before?

I noticed there was no plug where the display supposed to be, only some cables sticking out of the hole. There was no loose cables in the rear compartment.
How do I check the correct position of colours, plugs etc?
Later today I also noticed that the colours on rear camera view is also wrong. A red car behind me shows up as a "blueish" one. Is red signal missing and how do I check this?
I will check on the blue sea on the map tomorrow.
Previuos SW version was the same but with different colours.

I have read about coding of a replacement nav computer, what does the "VIN 7er" on the service menu/telematics settings mean?

> Previuos SW version was the same but with different colours.

This means it is NOT a software change! The dealer is talking rubbish.

If the colours on the rear-view camera are wrong then the reason is clear.

Two colours on the monitor have been swapped - ie: when they repaired the wiring, they mixed up two of the three colours.
The monitor is driven with Red, Green and Blue (RGB).

To determine which colours are wrong, print a piece of paper with three squares on it: pure red, pure green and pure blue. By pure I mean when you use the computer to generate the colours, use RGB values of 255,0,0 for red, 0,255,0 for Green and 0,0,255 for blue.
Label the coloured squares (in black) so you don't get confused.

Hold the page behind the car so it appears on the rear-view camera, and compare the pic on screen with reality.

My guess is that blue and red are swapped, as your green satellite symbol is still showing correctly in green.

Then either go to the repair shop and demand they fix their mistake, or fix it yourself.

The monitor has a blue connector on the rear, with numbered pins 1...18.

The relevant pins are:

1 = Red
2 = shield for red
3 = Green
4 = shield for green
5 = Blue
6 = shield for blue

You'll see 3 x coax cables going to these pins (or a number of unshielded wires, depending on how the repair was done.)

If red and blue are swapped, then remove and swap pins 1 & 5 (signal) and their shields, pins 2 & 6

That will fix the problem.

The nav should be coded to your car so it contains the correct vehicle information.
When the nav leaves the factory, it has default coding, where vehicle type is 7-series (7er) and VIN number is empty.
If the repair shop did their job correctly, they would have coded the nav to your car, and you should see your VIN number (last 7 digits of your VIN, in format AA12345) in the nav.
If this info does not appear, then the coding has not been changed, and the nav is in default factory coding.

This means that some items may not work correctly for your car.
eg: BMW Assist, Auto-Emergency Call, both require coding to work properly.
(default is no Assist, no Auto Emergency Call, and no SMS numbers or Customer Service Number programmed)

Also, the radio type, if not coded in the nav, may not be correct for your car (default is BM54).

And default languages (with no coding) are GB, DE and FR.
During the coding process, the dealer should ask you what languages you would like, or otherwise he will program with the default 3 x languages for your region.

If your nav was not coded, you should complain to the dealer.

I wish my dealer had a fraction of KiwiJochens knowledge..............I'm impressed!

Took the X out for a short trip today and blue sea shows up as orange, pls see the first picture taken. The orange strip is a local small river.
No colourprinter available at home so I can't do the printertest.

Removed the display and found the plug, see pic....... just one last question: Do I need to disconnect battery or can I swap the pins in the plug with just ignition off?

Don't have to disconnect battery.

Make sure you label the connectors - top is blue, bottom is white - even though it has a blue shell on it.
Looks like they did a good tidy job with the wiring.

I think the top connector is the video - check to see if the pins are occupied.

Removed the two display plugs.
Blue connection has 12 pins not 18. No pins in pos 5 and 8.
White connection also has 12 pins. No pins in pos 9,10 and 11.
Wires have no identification.

I haven't spoken to the dealer yet, as I thought I could fix it with your help.

Here are the connector pins and functions:

Pin assignments at plug connector X18801
Pin Type Description / Signal type Connection / Measuring notes
1 E Night light signal Connector, night lights
2 M Ground Ground point
3 A Positive activation, left tape Radio
4 A Negative activation, left tape Radio
5 Not used
6 E/A I/K-bus signal link Connector, I/K-bus
7 E Terminal 30 Fuse F72
8 Not used
9 A Negative activation, right tape Radio
10 A Positive activation, right tape Radio
11 Not used
12 E/A LCD data link On-board monitor


Pin assignments at plug connector X18802
Pin Type Description / Signal type Connection / Measuring notes
1 A Navigation video signal, red Video module
2 M Navigation video signal, red Ground Video module
3 A Navigation video signal, green Video module
4 M Navigation video signal, green Ground Video module
5 A Navigation video signal, blue Video module
6 M Navigation video signal, blue Ground Video module
7 A Negative signal, video module Video module
8 E Terminal 30 Fuse F72
9 Not used
10 Not used
11 Not used
12 E/A LCD data link On-board monitor

By using the empty pins as identification, you can see that X18801 is the blue connector, and X18802 is the white connector

You need to swap pins on the white connector.

Swapped the 4 wires.........VOILA.......everything normal!

Thanks KiwiJochen

Maybe I should link this thread to the dealer.....
