Must say Jayco could have made installing TV's etc easier had they run HDMI cables through the camper.
My friends HJ has the ent. ctr near the door, we removed the face frame and then removed the TV from the wall, there are mounting bolts holding the TV mount in place.
Once that operation was complete we then installed a HDMI from the Sat Box, drilled a hole to drop the cable behind the TV and hooked the HDMI to Input 1.
The Cable from the Sat box is mounted on the bulkhead upper shelf using coax from there to the Sat Box, in this case DirecTV.
It is imperative you install the right combo again in this Case DirecTV, in the settings of Sat Box you need to select the proper config. then allow the box to set up and hopefully you'll have TV.
Now you can re-install the TV Mounting Bracket, the TV, put the face trim back on and watch ur TV....
I was actually somewhat impressed that the In-Motion actually worked more or less, I'm sure on the highway more and on the windy treed back roads much less.
