I have a 53 S3 with Bose. My Bose headunit was replaced by audi under warranty. But now when i switch it on i don't get the Bose logo appear and also doesn't sound right.
is there a quick way to find out if the headunit is the bose one or are the both the same.
i think the one they replaced isn't the bose one.
does anyone know how to check?
