An interface and corresponding method, where the interface is connected via a first connection to a factory data bus of a vehicle which transports signals according to a first data format, and further connected via a second connection to a data channel of the aftermarket component which transports signals according to a second data format. The interface identifies a factory data bus type corresponding to the factory data bus, out of a plurality of potential factory data bus types. The interface receives digital signals from the aftermarket component via the second connection, the digital signals being in the second data format which corresponds to the aftermarket component. The interface translates the digital signals into the first data format which corresponds to the identified factory bus type. The interface transmits the translated digital signals in the first data format to the vehicle via the first connection.
