C.M Posted March 29, 2015 Share Posted March 29, 2015 Hi allNew in the forum, and a happy reader for quite some time.I have a Mondeo MK4, build date 13.10.2009, and I am trying to retrofit the original bluetooth. It is a Titanium with Convers+, Sony 6CD headunit and a AUX port in the glove box. The AUX wiring should go directly to the SONY radio through the QUADLOCK connector.Convers+ FW: 1007Sony 6CD HU FW: 05-06-01 The wiring for the BT module was already in the car from the factory, so I began to install it all.I installed the original microphone, the new voice/indicator stalk by the steering wheel, and the module 8M5T-19C112-AK.- Note: Firstly I tried the 7S7T-19G488-AE module - also with no success, and actually wanted USB connectivity, so I bought another one.Most of it works, I can connect the phone, browse the phonebook and so on, but I have no audio on calls. People can hear me, but no sound through the Speakers. Also no sound whenever I try VOICE. (VOICE is displayed on the SONY HU)Any suggestions? I am really lost, I have checked the wiring, searched Google, and a lot of other sites, but still no resolution.I did found this thread: http://www.fordownersclub.com/forums/topic/44084-retrofit-bluetooth-audio-not-working/ - Could it be related?Or is it the existing wiring which needs modification or something like that?Thanks!

C.M Posted March 29, 2015 Author Share Posted March 29, 2015 Note: I have the 8G9T-14N000-CB patch cable, which is for a car without BT connection. The 8G9T-14N000-AB cable or similar is for cars with an active BT connection. I think that is where the problem is at .. But if someone could confirm this, that would be great!Found this list on a polish site: 8G9T-14N000-DB - From: 01-09-2008 To: 23-01-2009 No call ± bluetooth connection, ICE-Naw. bogat.opc.

I know this is from forever ago but I’m having trouble with bt modules. How many wires does your patch have? Is it the 2 loops or more? hopefully you can still remember. thank you.
