Just got this email back from my dealer. Find it easier to email them as I then get everything in writing
-------------------
MP3 player is not yet available as a dealer fit option but when it does it
is not compatible with MF Steering Wheel. Nor will cars from 04 come with
the compatibility as standard.
As for the Power Socket in the boot, they deleted this option as it was only
there for the Mobility System for reinflating a punctured tyre with the
puncture repair kit. They realised that this can be done from the cigarette
lighter in the front which it standard so did away with the one in the boot.
The Product and Marketing Analyst that I spoke to at MINI informed me that
this is not going to become standard again, however, it may be possible to
fit this as a dealer option, price not yet available.

Can someone with a diesel try plugging a mobile charger or something similar into the 'hole' in the boot where the power socket should be just to see if it works?
