to any of the sources: radio, cassette tapes,
CDs, or DVDs. However, the rear seat passengers

seat passengers may listen to and control
cassette tapes, CDs, or DVDs through the

through the front speakers. The rear seat
passengers have control of the volume for each
set of headphones.
The front seat audio controls always have priority
