Please excuse me if the topic is in the wrong section.
So basically just got an A6 and while the car is very lovely, the standard audio system is underwhelming to say the least.
Is there a garage in the Luzern canton that can help do an upgrade for a fair price? Maybe somebody who had some experience can share how much it costs too.
I would also appreciate suggestions for the upgrade if somebody knows about it.
Thank you kindly!
