When I take the unit out and cover the hole, it looks like the car doesn't even have a stereo installed at all. Nothing to steal, not a target, no problems.

Apart from those expensive speakers that anyone can see installed in the back of your car. Empeg stickers on the windows also provide burglars a very nice option to pick out those cars which most certainly have (expensive) amplifiers and cables installed.
Oh well, if they want to steal anything out of your car or even your car itself, they take it away. Just make sure you're have a nice insurrance.
