I finally got tired of the terrible picture on our Axerra and mounted a 9” quad view monitor that allows me to see all three cameras at the same time or any combination I choose. Got the monitor from
https://www.rearviewsafety.com/ and love it!!! The monitor is plug and play, took less than 30 min to install, really easy. I left the Axerra in place and now use it just as a radio.
