On our 23f all Jayco ran was a one yellow RCA out of the did player over to the tv. So the tv was only used for the picture the sound came out of the speakers in the ceiling inside and/outside depending on what was selected. Though it was pretty basic, it gets the job done but composit video? The hdmi would have been a nicer touch, but we only use the DVD player for the kids when it storming and they are not ready to sleep with big storms coming through. And we had to have our original DVD/stereo replace because it would not play DVDs, something would pop and the DVD would randomly restart. Our dealer replaced the whole unit, so I got the newer model so not it has Bluetooth to stream audio to the stereo.
