Providing A/V audio to your car radio
This system offers you two ways of playing the A/V audio through your car radio
system. If your radio has AUX line-level inputs, you can attach the A/V audio output
connectors to these inputs with RCA-RCA interconnect cables.
If your car radio does not have these AUX line level inputs, another option is to use
the tuner audio transmission ability to broadcast the audio signal within your car
directly to the radio FM modulation.
