Hi mates!

This time I am showing you how to identify and retrofit a new Professional Head Unit wit built-in USB and Bluetooth features on my e93 from 05/2007

The improvement is very high!
Now, I have an USB socket and I don't need my iPod anymore because the USB...

I installed the microphone today. I used the included microphone (vw part). It works fine, but I had to use heated silicone glue to stick it into it's place, because it's smaller than the BMW part. otherwise it works the same.

I tried first to route the mic cable on the passenger side. If you are considering this, DON'T try it. The wire was about 20cm too short, and I realized this just when I got to the headliner part.
So I had to remove it and re-route it on the driver side. The wire was more than enough on this side because:
1) HU connector is on the left
2) I installed the microphone on the left side of the dome light switch
3) on the passenger side you have to go around the glove storage

Works fine now. I have to read to see what the voice commands do

The only problem I still have is the gong volume waaay to loud. I've coded kombi HU_VERBAU to radiostufe_2 for now, hopefully this will use older gong speaker (haven't tested yet) untill I figure out how to lower volume

Good progress!

So the vw connectors work on the radio?

How is the sound quality when driving? Any sound cancellation / quality issue?

the mic wires end with 2 pin connectors that you insert in the bmw plastic connector. Pins are the same vw/bmw, so they will work

Haven't tested bluetooth on the road, only when stationary and worked great, other person did not know I was on carkit

Because convertibles have the mic at the steering wheel column but others have it at the roof lights module!
Does anyone have any details on how to dismantle and install the mic in the steering wheel column (e93)? Do you need to remove the wheel, or can the housing be removed separately?

If you see the video, you will find how I did it!
It is not necessary to remove the steering wheel, I used an steel rod (bended) and I pulled the cover with it.

Any advice?
You have to change your production date to #0311 and then try again.

more info: I tried Steuergeraete_reset from tools32 and lost both BT and USB. I could not bring them back with SG_RESET

Then I started messing with ncsexpert and I found out something interesting, I think:
Codierindex_lessen reades and generates the NFW_PSW.TRC file
I added 6NN and #0311 to my VO, then did SG_CODIEREN. It failed, of course, but after SG_RESET, both options were back. I tried without #0311, only USB comes back

So I think somehow the radio does get coded even though it says FAILED. I am yet to find out if it does so automatically or I can change the NFW_PSW.TRC and be able to code it with my changes

I am attaching 2 files:
- report.htm (rename to htm) with the differences in FSW_PSW of the radio with bluetooth+USB enabled, one with disabled
FSW_PSW.txt - the complete file for the unit with BT+USB enabled

As you can see, there are quite a number of changes, I think a lot of them are because of the different year I had to use to make it enable USB+BT
Attached Files
File Type: txt report2.html.txt (15.6 KB, 272 views)
File Type: txt FSW_PSW.txt (230.2 KB, 719 views)

I confirm the same thing. If I keep my old build date I will loose everyghing. If I add #0911 ( for 09/2011) I will get the USB but not the BT.

Hi,

Is it one issue for the lound gong and reading the ECU with NCS without IFH error ?

I've try with v47.1 daten, but same problems.

Will the HU_verbaut in KOMBI disabled the loud gong ?

yes, changing HU_verbaut to radio2 disabled the loud gong, but you get the ugly sound from the kombi speaker (not too loud though)

If you have a very loud gong is because your unit is not coded for HIFI audio system (which is fitted from factory by default on US cars, here at UE it is an extra) So check if you have $676 at your VO and check if you have reseted the ECU with expert profile.

Of course, check if you have soften them with the musical note menu...

Both!

KOMBI:
HU_VERBAUT -> radiostuffe_3_4

2RAD -> SG_Codieren with the appropriate VO (#0311 + $663 + $6FL + $6NN + $676)

I'll reset with TOOL32.

Gong are a little bit slower but it's not very good ...

663, 676, 6FL, 6NN et all was write to FA/VO.

HU_VERBAUT -> radiostuffe_3_4 was OK before coding

Thanks a lot for reporting your experience in installing the microphone in the headlight unit. As far as I understand, you haven't got a car pre-wired for the microphone, so you routed the wire by yourself. Have you had to dismantle the A pillar airbag to do so? Which way have you followed to route the wire: from the radio to the headlight, or viceversa?

thanks!

I routed the wire from the radio to the roof light. I removed the rubber from the door frame, and this gave me access to the A pillar (there is about 6-7mm of open space covered by the rubber door seal). Take care with the airbag, the wire must not block airbag deployment. I removed the sun visor and roof handle and I could lower the roof a bit and push the wire all the way to the center front dome light
