Hi. I see no responses on this one.......so........I am not familiar with your coach or the Jensen DVD/Radio device specifically but a quick rear view of it on the net shows only one HDMI output from the Jensen.......which I expect is hard wired to your main TV HDMI input port. So I notice you had conversation with another person about the other TV’s in your coach but they did not confirm if they are equipped with HDMI inputs or not. Your coach should have an equipment list tag somewhere in a cupboard......find the model numbers of those other TVs (since they seem to be hard to remove fom the wall) and check on line via Google searches if they have HDMI ports or not. Likely modern TV’s all have them. Then you could look at buying an HDMI splitter (1 in 2 out are more typical) which would feed your main TV and one other TV all the time......no switch over required. You would also have to add the HDMI cable from main TV (new splitter co-locate) to the second TV. If you want all TV’s wired then a 1 in 3 out splitter device minimum is required and added HDMI cables. A powered splitter would also typically need an AC outlet. Hope this helps a bit.
