I don't know who is really generating the image on a screen, but in E83, if I plug only NAV module or NAV + TV, the menu/screen looks identical, only one more option is added (television). If I plug only TV module and unplug NAV, the screen and menu looks totally different. So it looks like on E83 NAV module is the main one. I had an idea of emulating the TV module on RPi and totally removing TV module, but I am not good at electronics so have no idea how to do hardware side the correct way
