Hiya guys n girls
Ok after initially being messed about



I am going to see another Cooper S this afternoon or tomorrow
This one is a 2002 Cooper S with 61k on the clock, 3 previous owners and a full BMW history
Its got the Factory fitted sat nav, so is the software upgradable? Some up to date maps would be good
Also, it HAS NOT got the premium sound system, so is the head unit an easier update?
I didn't know whether the sat nav goes through the sound system and whether its all integrated?
answers would be very welcome thank you
Chris
