Bigarm, yes. I'm writing from memory as my manual is on Rocky. The speakers toggle between CD, DVD, TV, and radio by changing the "mode."
CDs will play automatically, but you have to change modes for the radio (AM-FM-WX).
Now to get TV sound through the speakers, IIRC, there is an "input" buttom on the Genesis remote to change the input from AUX 1, AUX2 etc. and AUDIO1, AUDIO2, etc.
Turn your TV on and using the TVs remote set the volume at 50%. Then cut the Genesis on and start using the Genesis remote to change inputs. Pause at least 5 sec. between tries as it takes a second or two before the sound will come up.
I assume you got a manual? If not, your dealer has it. Mine was in a bag along with the remote and several unrelated pieces parts. The TV's manual was in a separate folder.
Let me know how it goes,
