You have an experimental or certified, newps?

I have a 182. You can't possibly be worried about velcro fer cryin' out
loud, can you? For the power I took the cig lighter plug and snipped off
the cig lighter end. Ran the two wires into the electrical bus and used a 1
amp fuse from Rat Shack. Had the mechanic sign off the power cord. My
setup is neat looking because I have an avionics access panel on the top of
the glareshield. The cord just disappears down there from behind the GPS,
you don't even see it from the pilots side.
