How to turn on GPS in Saab 340?

[Republic DC-9]

Sorry, newbie to this wonderful plane....how do I turn on the GPS?

After the automatic start feature the instruments all power up, but for some reason the GPS is dead and I can’t power it up.

I’ve missed a switch, someplace?

Thanks,

Steve

On the GPS, rotate the (C) knob.

Awesome...worked...had to do it from the console vs. the pop up - thank you!
