I have bought a professional headunit from a 2011 3 series but seller is unaware of the plugs behind the headunit.
Here is the photo;


Afaik,
White= USB
Black= Aerial
Yellow = DAB?
Green = ???

I will also try to find out their VO codes and post them here so it may help others to retrofit this into older 3 series.

Anybody has done any work / research on this headunit?

Thanks.

Yellow and green are confirmed for DAB (Digital audio broadcast), something similar to HD in states.

Now trying to find out the difference between yellow and green (why two connectors)?

That's newest Professional radio (RAD3) I think. It's different than previous Alpine.

This radio is equipped with BT (see sticker), so I assume it's the BT antenna connector.
Mic should go to connectors on the right, in blue plastic.

Thanks for the response.
There are two versions of these.
1- Bluetooth + USB (which has white and black connector only).
2- Bluetooth + USB + DAB (which is shown in the photo).

In Uk, mustard colour is for DAB antenna. Not sure about the green one and that is what I am trying to find out.

I'm responding to your DM here. For some reason the app isn't letting me send DMs to you:

It's an amazing colour. I have stored my car away for winter and don't have access to it but I'd you use my VIN and call any BMW they can give you the code. WBS53AZ0XMCG74694

@warcity thank you very much!! I really appreciate your help! Is it difficult to maintain the paint?

Sort of yes. You cannot take it to a car wash. It needs balanced PH shampoo (which car washes don't use). Stick to hand washing using special PH balanced shampoo (specific for matte paint) and use the two bucket method to wash and dry using micro fibre clothes. I use products from chemical guys.

I have also ceramic coated mine which I highly recommend.
