There's a small hole in the bottom center of the radio. You need a regular
screwdriver 1/16" wide by 12" long to reach the screw which is in the very
back of the radio. Unscrew the screw and pull the radio out of the dash.

More modern radios use a hex key (Allen wrench), and it does not have to be
as long as the ARC radios require.
