A6 [4A/C4] (1994–1997)
In 1994, the latest generation (C4) of the Audi 100 received a facelift and was renamed as the Audi A6, to fit in with Audi's new alphanumeric nomenclature.
The factory wiring uses an ISO plug.
The dash will only fit a single DIN radio.
Some vehicles are fitted with a factory BOSE system (the speaker grills will have a BOSE logo on them). These require the BOSE specific leads.
