It's not exactly a problem for me, just an enhancement.

My retrofits don't need a ZGW, so that's skipped.

I have an F25 radio panel, and "taking out" the volume knob requires desoldering the potentiometer off the PCB, which was not easy at all and I ended up basically destroying it. But at least I found out who makes the components and I'm currently trying to contact them to get information on how to make it work.

Your best bet is to buy the F30 aircon control unit module (very cheap) and connect it to a ZGW in your car. ZGW is obviously connected to the NBT.

Then take out the volume / button controller from it's F30 housing, dremel a suitable mounting position into the E90 housing and enjoy.

Unfortunately, I have since sold my Beemer.
