It is much simpler than that, methinks.

Audis and VWs have switches inside the ignition that detect
when a key is inserted. They use it to do things like: ring that
stupid bell when you open the door, turn on interior lights when
you remove the key, and (even) power the radio on some VWs.

If you look through a Bentley, you should see a small power bus
that is "on when key inserted". It won't handle much load, so you
may need a relay to drive a stereo.

Only my cat shares my opinions, and she handles plenty of load.
