Thanks for your response, bought from a garage, could not find CD changer in boot, left hand side of boot has the battery. Brochures and web info are very confusing. Mine is 6-speed, leather upholstery, 3-memory elec seat adjust, stub aerial on roof (rear). Because the car had not yet been showroom prepared they had disconnected the battery, hence ICS was not responding - needed input of Code No.
Hope the Sat Nav is there, does not really affect me - more my wife - her geography is dismal.
I am most impressed with the '166' when I had a close look at one then the decision was basically made - had originally intended to get Audi A6 or Merc 'C Class' - no contest once I had driven the 166.
Thanks for your interest - JonF
