Hi, sorry to be stupid but where is the sat nav cd player? I've looked everywhere and I can't find the thing!! I've looked under the seat in the glove box and cant see it anywhere...

 

Assuming you are indeed talking about the 1st Generation MINIs (i.e. 2002-2006 coupe, or 2005-2007 convertible), the answer is:

Under the passenger seat in the coupes, and under the driver's seat in the convertibles.

If you actually have a 2nd Generation MINI (e.g. 2007 coupe or R56), then you should probably ask this in the 2nd Gen Stock Problems/Issues forum, or the 2nd Gen Navigation & Audio forum.

(don't repost, I can move the thread for you if that's the case)
