The hi-fi amplifier can be coded and programmed. After the hi-fi amplifier is replaced, the new amplifier must be programmed and coded. From September 2010 a bus connection will no longer be installed for the hi-fi amplifier. Also replacement parts for the hi-fi amplifier that were bus-compatible until then will no longer be bus-compatible. The voltage supply can only be checked manually.
