Help mounting sirius radio

[sman]

I got it for christmas, and already got it mounted in my dodge, but cant figure out what to do for the camaro.

Im not sticking it to the dash, and the vent clip thing doesnt work worth a damn. I see alot of people put the receiver down in front of the shifter, Im not opposed to that, I just dont know how to physically mount it there, so its not sliding and bouncing around.

Stuffing the antenna inside the spoiler, seems to get good service there.
