I own a 2024 Keystone Passport 3300BK. I have a hardwired TV that is supposedly to control the sound system outside as well. It is a Connex TV? The remote has a separate section for “Zone 2” entertainment system but it does nothing when I try it. The dealership played with it for an hour and looked up stuff online to no avail. They claim the entire TV has to be replaced but the TV itself works fine. It does have an FM input that seems to do nothing but other than that it works. Anyone have this issue or know a trick to fix this? The JBL speakers are outside and do not have their own “power” buttons on them.
