Hi-Fi vs stock audio system
How do I know if I have the stock or the Hi-Fi audio system. The one thing I'm sure is it's not the HK!! My SA is not sure about which system is installed in my F30 335i sport. I live in South America and BMW has a specific standard package for vehicles in Latin America and some standard features here are optional in other countries. (ie: xenons, adaptive suspension, etc)
