Hi! Just bought a used E60, awaiting delivery. I had someone do a print out for me on the specs, and there's option 8SA - Country spec release of Navigation. Does that mean I have Nav or no Nav?I'm thinking it could end up being like phone prep & CD changer prep- means there's no phone or CD changer!Also how can I tell whether I've got bluetooth?Disappointing that a car of this caliber doesn't even have cruise control or the front armrest as standard...
