Thanks for all the information,
I am in Canada, and leasing the value edition of 328i. I think I do not even have the HiFi system. The audio quality is just unacceptable, it made my music library dull, unpleasant, and frustrating! Since I am leasing it, I guess there is no point I for me to do any mods.
Along with other issues, such as lack of enhanced Bluetooth, and undesired wooden interior, I really want to get rid of this lease.
