CD Changer for Primera MK.1V

Hi,

Have just ordered a new Mk.1V Primera diesel to reluctantly replace my 96 Primera, and am wondering if anyone as any experience of adding an aftermarket CD changer (ideally with MP3 compatability) to this car.

Failing that, anyone know the model number of the head unit, so I can start enquiring about a changer before the car comes early March?

Thanks

Chris
