Bluetooth Retrofit in 2001 X5, No Sound
 

Hi there,

I have a 09/01 X5, with Nav, no DSP and no phone pre-wiring. I have a 5th gen bluetooth module, and the Bimmernav kit for a non pre-wired Euro car.

I have completed the install, including ELK800 amplifier supplied by Martin at Bimmernav (as have no DSP). Phone paired with no problem (Orange SPV M600) including all phone book entries etc. Only problem is there is no audio.

I have tried adjusting the gain on the amplifier, but with no success. Please can anyone help / suggest what may be wrong?

Any help much appreciated.

Thanks,

Jeremy. :thumbup:

Access the radio module and see if you have phone audio on the pins noted in this link

Hi,

Where do I look for these pins to test?

Could this be a ULF problem? How would I test for this?

Also, the ULF cannot now read the phonebook, although it did manage to originally.

Thanks,
Jeremy.

The radio module is located down in the spare tire well in the rear.

The only way I could suggest to test if it a ULF problem would be to swap the ULF with a known working one and see if the problem follows the module or the vehicle.

Hi,

Thanks UCrewX5. But the diagram for the 2001 unit with Nav doesn't seem to indicate which pin to test for phone audio.

If I test the output from the ELK800 amp, what should I be looking for on my test meter?

I have tried remaking all connections, but still no luck.

Thanks,

Jeremy.:rolleyes:

pull out the radio and make sure that the telephone wires are plugged in

Same problem
 

I had the same problem yesterday, my phone wires were not connected to the radio (NO NAV) I pulled the cd player out and the connecter plugs into the main radio connector, it is taped to the main harness that plugs into the cdplayer.

That's a common problem for non-nav vehicles, but he has nav.

You are right, I have Nav fitted.

OK, so how can I check / test the output from the ULF into my ELK 800 amp, and from there to the radio / speakers.

This is really starting to bug me ... :confused:

TIA

Jeremy.

Hi Jeremy,

Sounds like the ELK 800 output connection is not connected, (to anything).

Simple way to test for sound, is connect single speaker up to the audio output from the ulf (or ELK 800 output).

The OEM BT audio out is connected via the "AUX in" connector on the back radio. (one of the smaller connector blocks)

I'll assume you have the 17 round pin connector.

for 17 round pin Connector

ULF Audio Tel +: 10 Pin Connector X01037 or X13321: PIN 8
ULF Audio Tel -: 10 Pin Connector X01037 or X13321: PIN 3

ULF Audio Tel +: 12 Pin Connector X13649: PIN 6
ULF Audio Tel -: 12 Pin Connector X13649: PIN 12

Thanks everyone for the contributions - I am narrowing down the possibilities, but am now stuck again as I don't know enough about the standard X5 wiring for a car produced 08/01.

I have confirmed that I have audio present on the ELK 800 amp outputs as required. I have confirmed that this audio signal transfers to the white X400 (is this the correct term?) plug on the existing main car loom. To my mind, this suggests that the problem lies between this point and the speakers, which leads me to think either:

1 - The connection is not already made in the standard car wiring; or

2 - There is a fault with the wiring.

I have tried to test for continuity with pins 3 and 8 of the plug which incorporates the CD changer inputs to the back of the radio unit under the spare wheel (thanks John and UcrewX5 for your info - vary helpful) - but can't find any continuity with the output from the amp, making me think there is a problem with the wiring.

Question 1: The plug incorporating the CD changer inputs to the radio (is this plug x13321 or x01037??) appears to run straight to the back of the CD player, with only 4 wires present - where are the other two which go to pins 3 and 8 for the + and - Telephone Audio Inputs (i.e. where are they supposed to join in the loom)??

Question 2: On cars with Nav, are there any other connections not made which I need to plug in (in the same way as referred to in the technical service bulletin for cars with no Nav)?

Question 3: Does anyone have a wiring diagram showing how the white X400 plug audio wires connect into the audio inputs on the radio?

Very grateful for any input anyone can give - I am sure I am not the only one who has had these problems.

Best regards,

Jeremy.:thumbup:

If pins 3 and 8 goto the cd changer then it could be that you have the 40pin Quadlock connector, in this case it will be the other pic and be pins;

Pin 6 Phone in +
Pin 12 Phone in -

Please confirm what tuner you have and the connector layout.
This is the worng plug/connector.

Do not connect the Phone outputs to the CD connector (radio side), they must be connected to the AUX plug.

In both 17pin and 40pin connectors, the "phone in" is connected to the AUX plug/connector, please refer to the pics I sent,

B in the 17pin connector, pins 3 & 8
C in the 40pin connector, pins 6 &12

If there is no connector plugged into this port then get one of these

and connect it up.

If the connector is there already with something plugged in, then pop the pins out and connect your phone outputs into the plug.

hope this helps

Since the car was not prewired for phone, it was built prior to 2002 (therefore you have the old round pin radio) and you do not have DSP my best guess is that the door speakers are not the dual voice coil speakers.
I bet once the door panels are off you will see loose speaker wire for the telephone system not wired to anything.

two options.

1) upgrade from round pin radio to BM54 radio in order for telephone to play via all speakers like the 2002 and up

2) change the door speaker on the drivers side to dual voice coil, or install another speaker in the door on the telephone audio wires.
This is not a common occurance as ALL US BMWS are prewired for phone, and only the X5 before 2002 had that old radio which without DSP used dual voice coil speakers. one voice coil for audio and the other for phone.

Problem finally soved!!
 

Hi,

Thanks to all who have contributed to this thread. I have finally managed to sort the problem out with Martin's help.

The problems with no sound reported on X5 retrofits often seem concerned with the lack of an amplifier (where there is no DSP). However, cars produced up until 09/01 (mine was produced 08/01) did not have telephone audio inputs on the round pin radio. Instead, audio from the phone was fed directly to the front door speakers via a second set of terminals to dual voice coil speakers.

What has transpired is that because my car was not prewired for phone, neither were dual coil speakers fitted in the doors. Instead, although the wiring was in place to take the audio signal to the speakers, the connections terminated behind the speaker, with nowhere for the audio to go.

I have now replaced both front door speakers with the BMW dual voice coil equivalents (part numbers 65 13 8 383 800 and 65 13 8 383 799), and hey presto! System works!

Thanks again to all who have helped. :cheer:

Best regards,

Jeremy :thumbup:

my x5 it's a 2004 i buy the kit and put everything
except for the ses jump plung the blue one behind
the cd changer ;because my car has it already. no sound
i can make call from the car to my house and i heard the homephone
ringing but in my car there was no sound then i change the ses jump
plug the one that came in the kit and everything work perfectly.
hope this might help

Excellent feedback. I'm glad to hear that Martin was able to help sort this out for you :thumbup:

Jez, Glad you got it sorted,

Martin certainly knows his onions :)

I'm amazed you needed the extra kit, my e46 was not pre-wired for the phone either, and I just made up my own retrofit loom (for less than £30 ($60) and then just plugged it in.

Plugged the loom into the ULF (connected to the radio module), mic, antenna and pair button, and hey presto OEM BT for less than £100 ($200).

No extra amps, speaker runs, nothing, it just worked, works well with the SatNav, and I now have Voice control too.

Must be a slightly different setup on the 01 - X5, sorry about the duff info.

Glad it’s all sorted mate.

contemplating putting Bluetooth in my 2001(12/00) - this definitely will help me better understand what I have to do. My Thanks also!
