As Espaced said, the unit is under the driver's seat (6 torx bolts to remove).
If it is simply 'off' is should say so on the display. It can be turned on by pessing and holding the top button on the remote for a few seconds.
I'm assuming the you don't mean the cassette player. If you had one of those, it would be in the glovebox.
