is it logic7 or not?
I just drove a friends 07 335i coupe with logic 7.
My 07 335i sedan from the US has logic7 on the amp front, what looks to be two harnesses, one fibre optic and the multiwire set-up. Further I have a centre speaker on the dash, sub covers but no sub under the seats.
What system do I have?
Of course my goal is to upgrade to atleast the logic7 system.
Any help would be appreciated.
