FAQ

Frequently asked questions

Do I need to remove the Symphony to get the serial?
Yes. The Symphony does not show its serial on screen, so slide the unit out with release keys and read the AUZ serial from the label on the casing. Unlike the RNS-E there is no screen route on this unit.
What is the difference between Symphony 1 and Symphony 2?
The Symphony 1 was an early 2000s unit. The Symphony 2 followed later with minor feature improvements. Both use the same removal and code process.
Which Audi models had the Symphony?
The Symphony was fitted to higher specification A4, A6 and A8 models. It sat above the Concert in the Audi audio line-up for its era.
