    Quiet sound coming from radio/nav area??

    I just bought a 09 platinum DTS 3 days ago. This is my first Caddy and don't quite know the nuances. It seems like every time I enter the car, there's a sound (similar to a CD spinning). It's very quiet yet, I have no clue what it is....anyone know? Is this normal?

    Thanks!

    I believe the disk begins to load when the door is opened, so it will be ready once the car is started.

    It's the DVD disk in the NAV system.
    It starts booting up as soon as you open the door.

    If you want to double check if that is really what you are hearing...
    Turn the car off, take the key out and BEFORE 10 minutes pass, turn OFF the radio.

    At the ten minute mark, the sound will stop.
    Open the drivers door and it will start up again.

    The Platinum undoubtedly has the NAV. But my DTS doesn't and it also has that sound (no CD's installed in the player either). Stays "on" after shutting the car down but stops when I open the door. I assumed it was some kind of cooling fan mounted behind the radio.
