That is par for the course for most dealers these days.
I had to have my G7a mainboard replaced because the control of my A/C units was erratic. They also decided to replace the display unit even though that was working fine. I tested it at the dealer before leaving and it worked fine. When I got home and it was getting dark, I went to turn on the lights and nothing happened.
I figured they didn't pair the multiplex switches with the new display unit. I tried pairing the switches, which is an easy process but it would not work. Called FireFly the next day and they determined I had a bad display unit. I had to call Thor and have them ship me a new one.
The dealer would have determined this had they even tried to pair the multiplex switches with the new display but they obviously didn't. Took a few days to get from Thor and 5 minutes to swap it out.
