Phone and Nav Audio Color Coding

Hi All,

just retrofited my E53 '05 (just had business cd/MID + BT) with a Sat/Nav MKIII (yes, i will eventually upgrade to a MKIV), but I am having the following issues:

1) No Phone AUDIO or muting of Radio
2) No Nav Voice

So, I started to inspect the cables and have worked out the following
1) I have to run a second MUTE wire (from another post) but I dont know where from/to
2) I think the cables are in the wrong "holes" on the connector.

The kit came with a full wiring harness, rather than the retrofit cable.

Looking at the connector that plugs into the Radio, 90% of the wires have been cut and joined (dont know why, but its all the ones on the small Black and White plugs).

I have checked the connections against this and most of it is correct, except the Phone Audo +/- and the NAV/TV +/-

The phone coloring is mentioned in the link above, so I found that those two connectors were in 5 and 11, rather than 6 and 12 of the Black connector, although this still didnt work until I find the "other" mute conenction. I am sure it is the mute, as when you dial on the phone, the Nav Screen shows you are in a call, but the RADIO (or other sound source) is still on, rather than the phone audio, which I am presuming the PHONE ON cable is connected, not MUTE (Please correct me if I am wrong).

And that leaves holes where the NAV/TV wires should go.

So, what I am actually asking is just the color coding of the Nav/Tv +/- cables as this is NOT in the link above. I have searched to the point of doing my head in. I even looked at WDS, but that doesnt have the conenctor mentioned in the above link (x13649).

What I think I can determine, they are Blue/Red and Blue/Brown, but then again, the speaker wires are that color too..

Can anyone help with the color of the NAV/TV wires and the "other" MUTE

Thanks,
Rob

I don't know what the colours are mate,

But the output from the phone should be (if you have a bm54), 6 and 12 (+ and -).

If you have a bm24 then it's pins 8 and 3 (+ and -).

There is only 1 mute and its pin10 on a quadlock (bm54) and pin 7 on the 17 round pin (bm24 radio).

You will also need the "tel-on", this is a must as it does some fancy switching in the radio module.

On the quadlock (bm54), its pin 11 on the 17 round pin (bm24) its 10.

The phones 54pin plug is as follows:

MUTE----------------------PIN 51 ULF
+12 V Direct-------------PIN 17 ULF
+12 V Switched--------PIN 35 ULF
I-BUS --------------------PIN 15 ULF
TEL ON-------------------PIN 33 ULF
GND----------------------PIN 36 ULF

Pairing switch------------PIN 32 ULF

Audio Tel + -------------PIN 37 ULF
Audio Tel - --------------PIN 38 ULF

1: MIC + -----------------PIN 1 ULF
2: MIC - ------------------PIN 19 ULF
3: MIC Shield------------PIN 21 ULF

Thanks for the information.. yes it is a BM54.

Well I found two issues after your information came and finding the correct colors from WDS (finally got that to wrok).

The Telephone Audio and MUTE (both of them, well one mute, one telon) pins in the Quadlock were in the wrong place. So I fixed them but had no affect, but then realised the wires were tied together on the radio plug and didnt go back to the main black plug. On the main black plug, I found the Phone AUDIO wires didnt goto the radio module either.

The short story is I fixed the cabling from the black plug (12 pin that supplies power to the harness and plugs near the NAV unit) and then the phone worked.

With regard to the NAV, those pins were in the wrong place. Put them in the right place on the quadlock, and everything now works.

Thanks again,
Rob
