  1. wiring diagram for connectors to monitor

    Does anyone know what the wire assignments are for the two connectors that plug into the back of the onboard monitor? I have the widescreen 16:9 monitor and the back of the display head has two connectors that plug into like this:

    They are both 12 pin connectors. I have a seen a couple of wiring diagrams that seem to indicate the assignments are this:

    BMW

    1-+12 VOLT IGNITION WIRE

    7-Speaker LF+
    2-+12 VOLT BATTERY WIRE 8-Speaker LF-
    3-GND 9-Speaker RF+
    4-пустой 10-Speaker RF-
    5-Speaker RR+ 11-Speaker LR+
    6-Speaker RR- 12-Speaker LR-

    But I'm not sure that is or either of these connectors. Anyone know what the wires are for on these connectors or a wiring diagram source?

    EXCELLENT! Thanks PSJR! where did you get this info? I was searching all over for this. (Maybe I used the wrong search terms on Google?)

  4. Anybody have the similar pinout/wire color chart for the sat-nav unit? (x1312 & x1313, violet and blue connectors on the back of the DVD unit). I'm returning a 12/99 car that was retrofitted with the TV tuner/switching module back to stock (well I'm keeping the upgraded MkIV navigation, but everything else has been removed). There's a homemade jumper harness in there, and lots of hacked wires, but I think I have enough connectors etc. to re-pin and splice things back to normal.

    I have this, but no wire colors to go with it...

  5. Maybe this might help a bit:

    In the picture for "Once the navigation drive has been removed, gently remove the whole trim piece." you can see the Trimble unit with the small coax/GPS/antenna cable with the one black connector (just to show what the MKII Trimble unit & attached wiring bundle looks like).

    Thanks SealBeach, your car's specs are just like mine!

    Appreciate the link, there's a lot of good stuff on Bimmernav, but unfortunately nothing I can use to piece back together the factory harness to the MkIV unit. I made some good progress today though, getting the speaker wires to the C43 reconnected, the reverse light taps put back together, and some other obvious wires re-spliced using unused wires that were just floating inside in the home-made E39 harness you used. I think you must have used an aftermarket 12 pin black (AMP style) connector to attach to the original wires, and moved the original blue connector over to the custom harness. So I'm at a point where it's just a matter of figuring out which color wires from the factory harness go to which pins on the blue and violet connectors. I know there are some balanced line level wires in there too, in addition to the colored 18ga wires.

    P.s. The SMB coax jumper for the CD changer arrived yesterday, thanks!

  7. While I don't recall the details, the TV tuner came with a custom cable. That cable was used to add the TV tuner into the mix with the Nav.
    I know, not much detail, that was over 10 years ago.....Of course, it started out as a simple mod to add the tuner, then blossomed/grew out of control from there!

    - thanks for letting me know you got that coax cable.

    Yes indeed, I believe this is the factory jumper cable from the site you linked:

    tvkit1.jpg

    Here's the custom E39 jumper harness that came out of your car:

    There's this one too, but it's obviously an aftermarket piece from somebody like bimmernav (goes to coder?):

    So this is where I'm at now:

    Aside from protecting the cuts on the speaker lines (from the now removed wire taps), everything on the right side half is accounted for and should be good to go (amplifier connections, CD changer wires, and three black antenna coax lines coming from the C pillars and parcel shelf area).

    On the left half of the picture, I need to build a factory blue connector which will replace the aftermarket black connector (which contains some black factory(?) balanced line level signal cables), and also verify and complete the factory violet and factory black connector's wiring. I've already spliced back in the yellow/red and yellow/white sections on the violet connector that were chopped out (using the proper wires from the un-used spares that I found in the custom E39 harness loom). There are also three loose unused wires with their original pins still attached (brown [usually ground], red with yellow stripe and white with yellow bands), so I need to determine which connectors and pin locations they go to. Lastly, there is a hanging purple and hanging black wires which are coming from the aftermarket black connector I need to figure out as well.

    Closer up view:

    The TV Tuner (which really should be called an audio/video switching unit with integrated off-air tuner!)

    OK, so here's a question for you all... Being a BMW collector, I happen to have an unmolested 2002 525i Sport with factory MkIV navigation sitting in my driveway. What are the chances I could use its blue and violet connector wiring assignments as a guide for this 740i restoration?

  9. Just wanted to update, that I got everything working on the 1st attempt! GPS locked into my location even inside the garage! CD changer audio works! (I'm guessing the coax SMB connector is digital audio, plus digital control signals, hence no 6 pin connector is present nor needed - that had me baffled for a bit). I did end up using my E39 525i MkIV nav computer wiring to help confirm some stuff, but the violet connector only had two wires, whereas the E38 had many more. I re-pinned what I could to match the E39, and everything worked! I was left with the black connector un-connected to anything; and it's two de-pinned wires still hanging loose, so I just taped them up and stuffed them along with the black connector behind the CD changer. If I ever find out what that connector is for, I will re-pin the two removed wires, and tuck it away further. I'm guessing it's for another module or something, and Sealbeach740 was just using it to get access to some more fused power, control, and ground lines.

    I'm thinking I might search for a proper TV tuner adapter cable and try to re-install the tuner as the factory would. Not sure if BimmerNAV sells the cables separately.

    Thanks for everyone's help!

  10. Hi there,

    I was searching for some stuff how to retrofit a navigation system into e39 540i which originally came with a business radio unit. I went to a scrap yard and came across an e39 530i 2002 with MK III navigation system. Anyway it looked like someone before me was trying to pull it out of the car but gave up for some reason. I took the challenge and I've managed to pull the wire loom from the car with LCD display, radio unit BM 53, amplifier Alpine. The only thing I'm missing is a GPS module. Unfortunately someone cut the plugs off the LCD unit and now I'm struggling to connect the cut ends of wires together. I saw the diagrams for the connectors in this post but it doesn't help me with my issue. I was hoping someone can help me.
    Also I didn't know much about retrofitting a MKIII system before removing it from a wrecked car so now I'm wondering how big of a job it is to connect it to the existing wiring in my e39. Any help would be greatly appreciated.

    Thank you
