I am in the process of replacing my Axxera AV614BH radio. Radio was installed in 2015 Thor Axis 24.1 so it is an older version from what you have. It is a double DIN head unit and is working just fine. Has a video input, HDMI, USB, Bluetooth, microphone, chassis wire harness (which is probably the same as the one you have in your coach). If you think this will work for you, please let me know.
I am replacing the Axxera with Atoto S8 Ultra Plus head unit with 10.1 floating screen. The Axxera is too small and has a hard to read screen.
