Is FZD necessary if I don't need BMW Assist??
Today, I went to the dealership and asked them if they can add bluetooth retrofit for a '08 328i. I do have voice commands already though.
They said they can get me installed the TCU with all parts and service and all of it for about $1,600 total.
One of the parts is the Switch Unit Roof (I think it's also called 'FZD').
I'll check with dealer later but from your experience, if I only need bluetooth w/voice commands (I don't need BMW Assist), do I have to buy the 'FZD' component necessarily? (this piece alone is about $390.00!!)?
Thanks for your help.
