Hello

Is it possible to retrofit Inside auto dimming mirror?

And what Hardware will be need?

- New Mirror
- Cable
Something else?

Where do I have to connect the cable?


Thank you

[softestplease]

I am also want to know if this is possible, has anyone successfully done it?

Normally you just need to connect power & ground cable and it will already work.
If you want full function, you need the reversing signal etc., but I'd say it's not really necessary.
Of course you have to buy an aut. dimming mirror, which is mechanically plug&play.

Hi

It is quite simple.

By a electrochrome mirror.
By the correct plug with cables (see etk.cc) from BMW.
Connect the loose ends of the cables with the rain sensor cables.
--> there are three pins (look into rheingold a there you can find the wiring plan)
One is ground, one is power 12V and the third is LIN Bus (violet/black).

The LIN Bus is necessary to get all electrochrome functions like no dimming when the interior light is switched on.
Good luck!

Terabyte, have you looked into this? I want to get this done too. Let me know if you made any progress.

Any idea where I can get rheingold from? Thanks

No. I haven´t done this till now.
But I think the best way is to put the wires to the FEM, like it is OEM

[Tcheslavie]

I have done it. Pretty straight forward operation. You can connect all wires to the rain sensor and it would work fine, however the mirror uses the KL30 power from factory comparing to the KL15 for the rain sensor.

[popi2009]

it is not that simple.

I have a rain sensor in my F20 - I have bought an autodimming mirror from another F20. If I connect just power and ground it DOES NOT WORK

If I connect it to another car that had the dimming mirror - the mirror works well

What I noticed there are 4 cables to work with

+12v
Ground
GEAR SENSOR
4th cable that works with map lights (map lights on - the mirror does not work)

what is funny on the gear sensor you have about +8V when you select reverse it drops for a second to 0V and then +8v again

Any idea how to make it work? Remember +12v and ground - NOTHING WORKS

BUMP...looking to do this on my car.

[boafriend]

I am interested in doing this too, in addition to the side mirrors, for my 2012 328i, but was told by a German specialty shop I go to that BMW told them it will cost $10k to retrofit since my car wasn't factory built with the necessary wiring. Apparently a lot of wiring needs to be installed That $10k is obviously bull, but I'd like details from anyone who has been able to do this.

Anyone have any success in doing this?

I found a thread from Bimmerfest but there aren't any more details aside from a pin connector map.

I used the pinout to use the wires of rain sensor. The dimmer works!

Hi all, I am trying to do this retrofit too and I just checked the bimmerfest post, my car is an F30 2015 320i Sport.

I have a mirror from a donor vehicle with options S430 (Interior/outside mirror with auto dip) and S431 (Interior rear-view mirror with auto dip)

This mirror has 4 cables: (I tested it with a power supply and compass and homelink worked fine, but no auto dip at all)
Pin 3 - (+)
Pin 6 - LIN
Pin 9 - LED for alarm status
Pin 10 - GND

My car only provides wiring for Pin 9 an 10, so the FEM does not know there´s a mirror.

Rain Sensor looks the same with the 3 wires, as described in that other post, the pinout should be:

Pin 1 - (+)
Pin 2 - Lin
Pin 3 - GND

Do you think if I wire it, this can work? I´m wondering how the LIN bus assigns a new LIN ID to the new discovered mirror if the FEM was configured to not have it.

Has anyone else tried this from manual mirror to auto dip?

Thanks in advance.

i have done this. check ista-d for wires setup there are 2 variants high and basic

Hi, I don´t have ISTA, do you think you can help me with the diagrams needed?
thanks!

Very easy if you have the rain sensor:

Rain sensor;

PIN Type Color
1 + Red/White
2 LIN Violet/Grey
3 Ground Brown/Black

Mirror;

PIN Type Color
3 + Red
6 LIN Black/White
10 Ground Brown

Coding info:

Without VO;

FEM_BODY;
FEM_01 > PfInternalMirror 3120 > ISP_EC = aktiv
FEM_01 > PfInternalMirror 3120 > ISP_KOMPASS = nicht_aktiv
FEM_01 > PfInternalMirror 3120 > LIN_ISP_VERBAUT = aktiv
FEM_01 > PfInternalMirror 3120 > PF_INMI_LIN_VAR = ISP_g_EC

With VO;
FEM with 431 option

Thank you very much! I just wired (+) and (LIN) to the mirror and it worked! Luckily I did not need to code my car as the LIN commands were already available in the LIN Bus to make the mirror work. Even the console intensity control is able to dim the compass intensity.

Thanks all for helping out and contributing, I can provide pictures or any additional details to anyone interested, just send me a PM.

I heard u only have to code if u want the dim to not work during reverse. Anyone confirm that?

I installed mine same way everything worked without coding but ista gives error. I coded fem and still get errors so while u can connect to rain sensor jus kno u will get errors n when u go for service it may cause problems. Didn’t for me but I told them not worry about anything electrical jus change my oil since I’m under warranty but afraid if something major was wrong they could try n blame that idk. U been warned.

I need your help !!
What is the Retrofit option in ISTA+ ? (is for F25 chasis)
To many thanks

Thank you all for the information. It works great. I didn't even need coding.

First I connected the mirror GND and +12V in test an thought the mirror was defective. Later I decided to install the mirror anyway and connected GND, LIN and PWR. I made a splitter cable from the Anti Condens Sensor of the Climatronic (also behind the mirror). It worked right away.
I didn't have a rainsensor but I do have Automatic Climate Control.

It worked without coding, even the revese signal disables the dimming!

[Gidimba]

Hi guys,
Where can I fond the cable for the auto dimming on the mirror?
