2001 Bmw 740il Radio With Navigation Wiring Diagram

  1. Wire diagram: After market Radio installation help

    Hi guys,

    I'm trying to install a single din in my 00 750il originally DSP/Navi. I searched and not able to find any wire diagram for the two plugs behind the navi display, 1 white plug, and 1 blue. I'm mainly working off of the blue plug, where the blue and yellow twisted pairs are speaker wires to the DSP amp. There are 6 other wires on the blue plug that I'm not able to identify, hope any of you guys have any knowledge please help.

    Thanks

  3. Chuck,

    I really appreciate the pin out for the harness, I'm trying to convert the pin numbers to wiring color code of the blue harness X18801, since I cut the harness. What I am interested in is +12V constant, Ground, and Accessories switch. I found +12V constant (pin 7), Ground (pin 2), but which pin/wire could I tap in for +12V ACC switch?

    1. Gray/Red - Nighttime illumination signal - Light Module
    2. Solid Brown - Ground **Ground**
    3. Blue/Black - Left tape voltage control (tape audio signal, blue twisted pair)
    4. Blue/Brown - Left tape voltage ground (tape audio signal, blue twisted pair)
    5. Not used
    6. White/light gray - I/K bus signal (I don't care)

    7. Red/brown - Terminal 30::Fuse F69:: **Constant +12V**
    8. Not used
    9. Yellow/brown - tape voltage ground (tape audio signal, yellow twisted pair)
    10. Yellow/black - tape voltage control (tape audio signal, yellow twisted pair)
    11. Red/Blue - Voltage supply Terminal R - Under loader Relay
    12. Solid black - Background illumination signal

    I pull all the audio electronics in the trunk yesterday, and the car electronics (headlights/interior lights) went crazy on me when I tried to started a few hours after, it would not start. Check the top battery, its only ~6V, what is draining the battery so quickly? I did left the door and trunk open for a couple hours. Anyways, I disconnected the top battery and put it in the charger the last 3 hours, trying to get it fully charge.

    Thanks Chuck, you're the best moderator I've seen in years.

    UPDATE: So I got the car to start and all the problems went away as expected/hope for after the top battery is fully charged.

  4. Terminal R is the accessory (position 2) on the iggy switch IIRC. Check for voltage on the red/blue with the key in different positions. - - - Updated - - -

    Edit: Looks like that's actually a red/violet on pin 11.

  5. One last wire I fail to ask, which wire should I use to send the "remote turn-on" to the trunk? Can I use pin 6 to send the signal to the trunk?

    I appreciated Chuck...!

  6. Can't answer that. Best wait for someone who has done this work before. I wouldn't mess with the I-bus in any way however.

    Theres a white signal on wire coming from the largest plug on the DSP amplifier in the trunk. Saves you running a wire from front to back.

    I saw the white signal wire on the large plug, but will it still be functional without the DSP system? How is that white white get the turn on signal?
  9. Do your self a BIG favor..just rewire it all..

    I ran a entire new Harness from the amp up to my aftermarket head unit (RCAs,all speakers, power, remote, illum, ibus, reverse cam, bomb blast button, champagne tray and guacamole)

    If you are still runing the ORIGINAL 4ohm DSP speakers i bet they are toast...all the woofers shot.

    I ended up going MB Quart 6.5 components with tweets and a new 4 channel amp...to my aftermarket headunit. 100xs better than a 15 year old speakers!

    I only ran RCA'S and remote from the deck to my 3 amps in the trunk, two, 4ch. And 1 mono for single 15 IB. All speaker wires are already in the trunk to the speakers. I'm running active crossover, to 2 sets of image dynamics ctx65.

    Whenever we start running multiple amps and new HU we always ground the HU to the same ground as the amps and use the same "battery" power. What I do is take 14-16 gauge wire 1 yellow, one blue and twist. Then 2 14-16 gauge black wires and twist. Connect the black to the ground where you have the amps grounded to, take the yellow and connect to one of the amp power connections and take the blue and connect to the same amp remote turn on. Use a jump wire to seperate amps. Run the 2 twisted pairs along with the audio interconnects and connect to the HU. The only wire that you pick at the HU is the ign wire, leave the rest of the harness alone. In the trunk where the dsp amp was, solder new speaker wires to the wires driving each speaker and insulate with elec tape/liquid. I don't ever cut factory plugs off with these types of installs. The reason for running the ground/ign/rem from the amps to the HU is to combat any introduction of noise due to multiple ground points. Plus the install is nice and clean and can be taken back to stock if ever required. I will also use a quality set of audio interconnects. Good luck with your install.

    320is,

    I appreciate your expert advice, and I agree with everything you said. However, I am not running the power and ground back up to the head unit. Solely because I have never experienced noise problem with using different grounding for the head unit respectably to the rest of the system. I am grounding all my amps grounds the same point as well as power from one distribution block, because I have experienced noise issues like you mentioned with different ground points for the amp. Again, I also agree with you that none of the harness should not be cut, as it is not necessary (though I did cut the harness behind the deck for probing purpose). I will be tapping in the rear harness for speakers, and solder everything in place. I just don't connectors when doing audio install.

    Thanks for sharing your expert opinion.
