Just joined the forum - "GREAT" ..... thankful to have another source of information from owners. I just purchased a 2020 Thor Miramar and getting ready for our first trip .... having problems with the Rear Camera - Audio. I was told during orientation there was no audio. The Camera VCMS1401 manual indicates there is. Contacted Thor Customer Care and they referred me to Axxera Tech. Svc., who just told me how the system works - I already followed the Axxera Sound operation instruction and already knew. Apparently the system is suppose to work with emergency brake off and shifting into reverse. Had my wife in the back and gave her an opportunity to say anything about me in a "loud" voice. Didn't hear a word she said ..... WHOW! My next step will be to look in the back of the Axxera to make sure the Rear Camera Audio is connected. Does anyone have any suggestion?
