How do I remove the voice arm switch from the steering collum?
 

I have a 2002 S430 that I installed the Mercededs Timeport phone and voice in it last year. I just removed the system from the car. But I can't figure out how to remove the arm switch (that has the mic pictured on it) that comes out of the steering collum. Can anyone help?

Thanks,

I have a similar issue I installed it and need to remove. MB suggested push in and turn upwards, the reverse of installing.
