Hello!
I want to install a radio in my 2003 Mercedes C180 that doesn't support steering wheel controls. It is a Denver radio.

I guess I just leave the upper, bigger isoplug, unplugged then.

I wonder, do all the buttons on the steering wheel stop work if i do this?

On this car the oil check is on the dashboard, controlled by the steering wheel controls, so donīt want to lose this.

But the volym and next track control is not necessary to me.

I would be very happy if someone could answer this
