As for your question about keeping it there are plenty of threads here that outline the common problems and cost to repair. They are pretty reliable though.

Thank you so much @momoboy. I was also looking for that piece of information
to reach that fibre endpoint. Do you know any DIY doc link for it?
I can try and take a look myself first.
Btw, I asked the BMW dealership to identify it, they will charge $300 cads for it. I also asked a local BMW repair shop, they returned to me
with "you have to buy a new amp or used one"
I don't know how they test it. they did not give any details
Actually, they did not charge for anything. I guess, for the electronic issues,
BMW official service is the way to go.
