system
The AUX-AUDI.01-RCA part of the Carmedia system is an audio connection cable used to connect an external audio device, such as a smartphone, to the car's stereo system. The cable is a standard 3.5mm connector, with one end terminating in a pair of red and white RCA cables that plug into the car's audio system. The 3.5mm connector on the other end allows for a simple and convenient connection of any device that is compatible with the 3.5mm audio connection.
