Stick it in a small pouch with a flap, then Velcro the pouch to the center of the dash.  I had a mini-age, knife, and a rescue tool in mine.  Had it low on the dash, and mostly out of sight and mind.  Was handy for both the driver or passenger
I now have well modified AMK PSP kits and the tool pouch in each door pocket.
