Setting the heading on the Cessna 182 RG

Hi,

I've having some problems finding any information on how to enter the heading on the above. plane. I bring up the radio stack and can enter the ATIS frequency, Runway ILS, transponder. However I cannot find anywhere to enter the heading so the compass gyro points in that direction.

I've tried the plane handbook and tried google but cannot find anything.

Can anyone help with this?

Thanks,
