My 2022 Navion had terrible musical sound, played in mono through the center speaker. It sounded like a radio out of a 1950s Ford. I found a fix for it, here it is on on YouTube. It worked, and now it sounds just fine, playing through the other four speakers.

I have a 2022 Navion. I can only fill the propane tank up to 3/4 full. My dealer says that’s normal, that’s just the way it is. Seems unlikely to me. Is anyone else seeing the same thing, if you fixed it, how did you do that?
