Help - newbie on navigation

Hi, I have a Japanese import Z4 with a navigation system that I am going to replace with a Mk4 sourced from eBay. But I found out that the connectors at the back (the blue and burgundy ones) are different. Can someone tell me the part numbers as I can't seem to find them anywhere? The local BMW office in Singapore is not of much help either. They gave me a part number for a complete wire loom when all I want are the 2 male 18pin ELO connectors.

Any help here is much appreciated. Thanks.

Hi,

It sounds like you have the Japanese Z4 with the Japanese system.
I have converted some of these from Japanese to Euro system.

Note you must use Mk4, the Mk3 cannot work in a Z4.

The 18p connectors are available from BMW - refer to the www.realoem.com website, see this page here:
http://www.realoem.com/bmw/showparts...80&hg=61&fg=15
You need item #9 (18-pin connector), x 2 connectors
2 x pieces Part 61131383852
Plus you need some pins, about 4 will do, because most wires can be removed from the Jap plug and inserted in the Euro plug:
4 x 61130005197
You will see some wires (power, ground) have to have new pins fitted.

Remember: you also need to join the FM antenna (it loops through the Jap nav, it is used for VICS reception in Japan) once you disconnect the Japanese nav, otherwise you have no more radio reception, (or reduced radio reception). I used a custom-made SMB-SMB coax cable, 100mm long

Also, the Jap GPS antenna connector (type: Fakra) will not fit the Mk4 because it does not have the right locking mechanism. I used another SMB-SMB extension lead, also 100mm long, and used tape on the Fakra-to-SMB connection to secure against vibration.

Do you know how to change the radio from Japan mode to Oceania or European mode to work in Singapore?

If you also have telephone, the phone can be changed as well, if you want.

Hi KiwiJochen, thanks for the very fast response. The unit I have is a DVD Mk4 from a guy in UK. Thanks to all the information I found here, I made sure the unit is for X5/E46/E85.

I clicked on your link and found this;

1. 61131383852, UNIVERSAL SOCKET HOUSING UNCODED, 18 Pol.
2. 61130005197, Bushing contact, 0,2-0,5mm
3. 61131383650, Lock
4. 61131392244, Covering cap, Z-Code

Am I to get only items 1 and 2? From what I saw in the catalog, it does looked like all 4 items are needed to assemble into one connector, but I could be wrong.

I may also have a problem getting those SMB connectors locally. If I splice and connect the FM antenna, do you think the reception be affected? Thanks!

Those are the old-style connectors. Use your chassis number in RealOEM, it'll probably have the new style connectors, same as what is fitted now (tip: look at your own car to see the connectors in real life)

As for coax cabling, I wouldn't destroy the wiring if it was my car.
If you do a neat and tidy job with the coax, it won't affect reception. But I wouldn't do it to my car....

As for the GPS antenna, you need an adapter. You have no choice.

SMBs can be found in every country, go and contact your local specialised coax cable manufacturer. SMBs are used in the mobile telephone industry for base stations, you won't find them in a hobby shop, but you will find them at a cable manufacturer.

And Mk4 navs are the same world-wide, so no problem there. Make sure you program it afterwards to suit your car (NavCoder can do this for you)

Hi, I will get those parts this coming Monday and get on with it and see what's next. I agree with the part about the antenna connectors. Will try looking for them locally, otherwise on eBay.

Thanks again KiwiJochen.

Hi, I took out the old unit and immediately ran into some problems with the wire assigments. Some of the wires are different in colours between the circuit diagram I downloaded and the ones found in my car.

I can't find the VMR, VMG and VMB wires, Brown/Red, Yellow/Red and Yellow Brown wires for X1313 (Blue Plug) and I don't have the Blue/Yellow and Violet/White wires needed to assemble X1312 (Burgundy Plug).

I took note of the existing 20 Pins plug and pin assigments;
  1. White (from Cable set 1)
  2. Red (from Cable set 1)
  3. Blue
  4. Grey
  5. Not used
  6. Blue/Red
  7. Red (from Cable set 2)
  8. Grey (from Cable set 2)
  9. White/Red/Yellow
  10. Red/Green
  11. Grey (from Cable set 1)
  12. Black (from Cable set 1)
  13. Clear (from Cable set 1)
  14. White (from Cable set 2)
  15. Not used
  16. Blue/Brown
  17. Black (from Cable set 2)
  18. Clear (from Cable set 2)
  19. White/Green
  20. Brown
The picture here will tell a clearer story; I am a bit lost with that 2 thick and black cable at the top of the picture.


Also and if look at this picture you will see 3 Fakra SMB female connectors. Can you tell me how to assign them, I'm lost here too!


In addition to the Navigator, my car also came with TV, CD Changer and Minidisc player.

Thank you.

Well done for taking such good clear photos, it'll help me explain what you have to do.

Firstly: antenna sockets

Violet = Unknown. Jap toll charge system I believe. Not used for Mk4.

Blue = GPS antenna.
You'll note it doesn't fit as the Facra plug requires a Facra socket to lock the connector into place. What I did was use an SMB-SMB extension cable (100mm, m-f) and that worked beautifully.

Black/purple (twin connector) = AM/FM radio antenna.
One side comes from the antenna, the other side goes to the radio. It's used to feed the Japanese VICS traffic info receiver inside the Jap nav. You need to connect both sides together, because with it unplugged, you have disconnected the antenna circuit for the radio. TIP: use an SMB-SMB custom made 100mm cable for a clean, reliable quality solution. That's what I did.


Nav connectors:
(blue = blue Mk4 connector, burgundy = burgundy Mk4 connector, p = pin number)

Dead-reckoning input signals
19 White green = F_DFAHR rear right wheel speed pulse = burgundy p10
NEW-WIRE = RFL – reverse light = burgundy p1

Power and kbus signals
10 Red/green = terminal 30, permanent +12V = blue p1
20 Brown = terminal 31, ground = blue p10
9 White/red/yellow = K-BUS – kbus data bus = blue p3
NOTE: you will note the power pins are too big for the Mk4 connector. See note below.

Video signals
7 Red = R75 – red video = blue p4
8 Grey = G75 – green video = blue p8
17 Black = B75 – blue video = blue p13
14 White = SYNC – video sync = blue p17
18 Shield (clear) = RGBGND – video cable shield (ground) = blue p15

Audio signal
6 Blue/red = NF+ voice signal = blue p9
16 Blue/brown = NF- voice ground = blue p18
(audio wires are a twisted pair)

The left over Japanese wires are for Japanese functions that the Mk4 doesn't support (like Japanese phone). Leave them disconnected.

All pins, except for the power pin, are the same type of pin used on the Mk4 connector. So you can just unclip the pin from the connector and transfer the pins, one at a time, from the Jap connector to the Mk4 nav connector. Very easy.

The Jap power pins are physically too large for the Mk4 connector. Cut them off, and either fit new pins, or cut off a pin from the left over Japanese wires and use that (they will never be used anyway). Solder the new pin to the power and ground wires.

NEW-WIRE you need to fit a new wire from the burgundy pin1 (reverse signal) to tap into the reverse light wire. Again, use an unused Jap wire as a source for the pin. Luckily, the reverse light wire sits in the wiring loom in the boot, behind the nav down on the boot floor, close and accessible. Look for the blue/yellow wire. I cut 2mm of insulation of the blue/yellow wire, soldered my new wire to it, and then insulated with liquid insulation. Worked well - a bit awkward in the cramped space inside the boot, but I managed.


Once you have cabled it all, plug in and test. The nav will work immediately, and will recognise the radio and TV and CD changer. You can leave off the GPS connector temporarily if you don't have an SMB cable yet.
Go back into the Radio Service Mode, now that you have the Euro Mk4 nav, you'll have more options to choose from in the radio.

NOTE: Japanese telephone will NOT work, as the Jap phone is not an ibus phone. But if you ever swap the Jap phone for a Euro bluetooth module, it'll work.

If it was not for KiwiJochen, hundreds of people all over the world would be lost in the world of BMW Navigation!!!!

I'm mainly over at BimmerBoard, but KiwiJochen is all over the place, many online boards are lucky to have him as a member, god know if he didn't drive BMW's where the BMW community would be

Props to Jochen
