Somewhere earlier I read a post where someone was looking for information on getting the surround sound to work from the television. This sent me searching in my Monarch to find out why my surround sound didn't work with the TV. In the cabinet above the driver seat I found a red, white yellow audio video cable that had one end connected to nothing and the other end went over into the front pillar. I fed the loose end over to the rear of the TV and plugged in the red and white into the audio out jacks on the back of the TV. I put the dash radio on aux 1 and instantly had surround sound from the TV.
I hope this helps someone else.
