DIY - Custom Bluetooth for pre 2002 E39

Installed set up with TCU. Everything works great.

I love my E39 2001.
This is a very interesting option for an upgrade.
For me this does not appear to be a DIY.
A drive to Toronto would be fun though.

Thanks for a brilliant thread. I have made a loom to match the pin outs in the first post and pluged in my TCU and it is showing up on the monitor (16:9) as Telephone yet when I try and select it from the menu screen i just stay in the menu

Any pointers?

The car is a 2000 M5 with Factory nav and DSP

i had the BMW GSM phone originaly which i have removed

For those who have had the same problems as me i have now fixed it. I noted at least 2 users had the lack of Pins at 21 and 22

These are in the 18 pin connector under the arm rest and need to be either re routed to the boot or found else where in the car. I used 2 of the now un-needed cables in the loom and looped it back to the 25 pin connector and then into the 45 Pin in the correct place.


25 PIN 45 PIN
3 Ground ----------------------> 36 Ground
4 Voltage ----------------------> 17 Voltage
5 Terminal R ----------------------> 35 Terminal R
10 Tele Mute ----------------------> 51 Tele Mute
14 Microphone Negative ----------------------> 19 Microphone Negative
15 Positive Microphone ----------------------> 1 Positive Microphone
19 Positive Front Speaker ----------------------> 37 Positive Front Speaker
20 Sheild ----------------------> 21 Shield Microphone
25 Negative Frout Speaker ----------------------> 38 Negative Frout Speaker

18 PIN (under arm rest) 45 PIN
9 IBUS ----------------------> 15 IBUS
11 TELE ON ----------------------> 33 TEL ON

I have no eject box harness in my 2002 BMW X5. I saw in this post that for the 18 pin eject box connector, "pins 11 and 14 must be connected."

Does this mean:
A. pins 11 and 14 should be connected to each other (aka jumper)
or
B. pins 11 and 14 must be connected to some other two connections?

I have no audio for the Bluetooth at the moment. ULF box connected, SES jumper, and I've got DSP amp and Business CD radio.

Thanks!

The information I am providing to you are all based on research as I do not have the same setup. Follow at your own discretion.

With that disclaimer out of the way, let me know how that works and pm me if you need any help.
