Dave,
Be careful where you install that radio.  My car was broken into the night after I installed mine - the night of the January Jaunt to be exact when I was parked on Dufferin at Bloor.  Luckily I had taken the the remote head in with me that night and the actual radio is hidden... But the thought of it disappearing already is making me wonder if I should have it insured (ick!).

Anyway don't make it too easy to remove.  On my CD player I run some framing wire from the player base to the firewall - the radio doesn't go anywhere until you dive under the dash and cut it.
