I have a 2010 mk2.5 focus Titanium in which i have retrofitted the Ford bluetooth unit ( version AM). The car did not have bluetooth capability out of the factory. The phone is bonded with the sony DAB headunit and can make calls but there is no audio through the speakers. Similarly no streaming audio is heard from the music player.

Having researched via Google, i am aware that there may be a wiring compatibilty issue but have not been able to find a solution.

Can anyone help?

Thanks

Phil

So you retrofitted a module 8M5T-19C112-AM? into the car and all the wiring was already inn place?

 

Behind the glove box to the left you will see a wiring loom which has a Gray foam protector around it, peel back the foam and you will see a Gray connector with some wires looping in and out of it. It may be wrapped in electrical tape which will need to be removed.

You will need to replace this with an audio patch cable  Finis 1592580  which can be bought from Ford, £9.31. It just has more wires looping,

The new patch cable routes the audio through the module so that the music can be muted when making or receiving a call,

 

Is your microphone working? as there is a patch cable for this as well!

Gaz RS, thanks for your help and the photos - much appreciated.

 

The module I have is a 8M5T-19G488-AM (ebay special)  - is this a problem?

 

I have not managed to install the mic yet as I seem to have got the pillar mounted one instead of the unit in the courtesy light, so will have to go back to Ford to get the right one!. I will pick up the patch lead at the same time.

 

Do you also happen to have the Finis code for the Mic Patch as well - just in case.

 

Thanks again

 

Phil

The only problem with 8M5T-19G488-AM is that the module does not support usb or A2DP streaming.  

 

The mic patch cable, finis 1592586  is £12.67 and is located just below where the audio  one is, below the Gray foam. There is nothing plugged into it so it's just a case of plugging the patch cable ln.

Hi Garry, I'm new to this club and this is my first post and I've got a 2010 Focus Titanium Estate which is prewired for BT/VC I'm in exactly the same position as Phil and after a ridiculous amount of research prior to fitting the necessary kit I was completely unaware of the necessity for audio and mic patch cables... so thanks! I've found the audio plug and its exactly as pictured. However, for the life of me I cant find an empty plug anywhere under the audio plug or indeed anywhere behind the glovebox! Am I looking in the wrong place? Any Help would be appreciated Joe

Hi Joe, maybe this other pic will help, it shows the connector just further down the loom from the audio connector it has 4 black and 4 red/ white wires going into it. Which head unit do you have?

 

My focus is a 59 plate, I've read that at some point in 2010 ford changed the wiring!

Cheers for the response.I've got a single  DAB Sony. I haven't connected the mic yet so I'll give that a try without the audio working, perhaps the mic patch plug is not needed on this model? I read somewhere Ford changed the loom layout too but not what they did with it. I'll let you know what happens.

Ok, Mic works so I guess the plug isn't an issue on this loom? May be something to bear in mind for future retrofitters? I'll get the audio plug next week and then see how it goes. Thanks for the help anyway Garry.

By way of an update I fitted the microphone, and the audio patch lead and the system works fine now.

 

Like Jo, I couldn't find the 'empty' connector for the microphone patch lead but seems this is not needed. Mine is a 2010 Focus with a build date of 22/1/2010.

 

Thanks for your help Gaz

It's quite easy to do with a modified ELM cable and ELMConfig, let me know if you need any help. You'll need the stalk with voice button.
