and I think there is enough info there for me to get started. I just need to get the # off my head unit so I make sure to order the correct adapters to install the mic.
At least I'm off that merry-go-round of mulfs and combox's.
Thanks again Alex
PLEASE post ANY updates as I am in the exact same boat as you... a 2011 328i, born in April, same radio, no mic etc. Any infor you find while doing your install is much appreciated! Thx
