Hi - just been installing a Gen 13 ULF + new loom into the RR. Got it all working and paired with the iPhone BUT the last bit of the puzzle is the mic connection. Rather than re-run the new loom through the car I thought I would just jump onto the old loom wires to get to the roof mounted mic.......but can I trace them NO!!!!!

The car has the original phone prep wiring and mic in the roof - its a 53 plate vogue with sunroof. the roof mic is connected to the three pin plug and I have tried to trace it through to the 16 way blue plug in the rear - with the amount of spaghetti wiring things have been a struggle. Using a wire tracer seems to react to more than one wire......

Having a quick look at old docs it appears that MIC+ are pins 9 & 11 (Yellow) and MIC- are pins 8 & 10 (Black). Check to see if the colours of these wires match first 2015 L405 SDV8 Autobiography, Indus Silver with Black Pack.

Either I'm looking at the wrong plug or things are very different. The old seimens telephone connected to the old telephone unit with a blue 54pin plug (that I have assumed has the three mic wires in it). I have removed the old telephone unit and replaced it with a new Gen 13 ULF and a modified bit of loom from l322.com that connects to the large white plug for power and iBus and has plugs for an eject box (not using) and the three wires for the mic.

You mentioned the old siemens unit..............do you have a small silver module bolted under the Nav Computer? This is the voice recognition module that came with the orginal factory fitted phone kit, the newer bluetooth modules have "voice" bult in them and this separate module is now "surplus to requirements!" The 26 pin plug that goes to this module is the one I am referring too. 2015 L405 SDV8 Autobiography, Indus Silver with Black Pack.

Excellent - I will have a look first thing in the morning - so assuming it is the same I use the two yellows together and the two blacks....whats the other black in the three wires for the mic - is that just to ground? "On first name terms with my local Dealer......now."

If you are using a continuity tester with the mic plugged in, you'll get continuity through the mic so more than one wire will react. I don't quite understand where you are having difficulties. The chart on Adam's site has it listed: pins 52, 53, and 54 in the 54 pin plug in the original configuration are the mic. If you had the BitII phone, those wires should be there and be active. Wiring diags are all in the RAVE. RRC 2Dr, RRC 4Dr, P38, and 2 L322s (wife thinks I'm nuts - prob right, too) |

Yep - not doubting Adams chart but when you have failed to get it working after following what is a detailed pinout you start to doubt things The wiring colours didn't match on the 54pin to those at the mic hence the confusion. I will have a look at the old voice module and see what I find.

If you've removed the voice control module then that's your problem. The 3 mic wires go directly to the Phone module (BITII or ULF) w/o the voice control module but are diverted into the vcm when fitted - from there 3 other wires go back out and continue to the ULF.

Isn't this what I have been saying? Anyway as mentioned dont leave both new ULF and old voice module connected for too long other than to test a phone call NOT voice commands As I understood it if you had the old siemens phone fitted with the cordless handset in the centre console (as I did) then you definately had the voice module. If you didn't have the phone kit supplied as a factory option then the phone wiring loom was only factory installed in model years 02 & 03, this loom had the 54pin plug and the 26pin plug for the voice module and a mic up front in antisipation that dealers would be able to sell it as an upgrade/accessory. The wiring loom was dropped as standard from 04 onwards due to low up take hence the reason why from 04 onwards the "face" button on the steering wheel to control the voice commands was also missing. Net result is this an easy problem to resolve. 2015 L405 SDV8 Autobiography, Indus Silver with Black Pack. SWMBO: 22MY Defender 110 HSE X Dynamic, Gondwana Stone.

Huh. Sorry - didn't mean to step on your toes... Leaving them both connected doesn't really pose any great potential for damage. Both modules simply transform voice commands into i-Bus commands. It's actually kinda funny to have a schizo car. RRC 2Dr, RRC 4Dr, P38, and 2 L322s (wife thinks I'm nuts - prob right, too) |
