For all of you who have experienced the "DEVICE NOT FOUND" error on their screen, the problem is the USB hub at the bottom of the center console. My 2019 was out of warranty when it failed. I found you can purchase the hub from Ram for about $40 and it is an easy install only removing a few bolts and pulling back the center console to get to it. Here are a couple pictures showing the "C" inputs that failed with horrible corrosion for no reason. No liquids ever touched this hub.
Get some Corrosion-X, spray or even the gun formula. It's amazing on electronics with corrosion and even water protection of electronics that aren't designed to be waterproof. RC people who use electronics in water having been using this stuff for a decade or two.
We run 100 mph electric RC boats in salt water, and Corrosion X is the reason why we can. It's like WD-40, but can waterproof electronics and even return damaged electronics to working order. We spray non-waterproof exposed circuit boards with this stuff and it makes them water resistant, even in salt water. It will also clean and make corroded electronic connectors work again.
Just buy a small can for $10-$20 bucks, spray all the corroded connectors. Let it sit a bit, down wipe down to clean off the corrosion. Then lightly spray again and leave wet, it will prevent that connection from corroding again and likely function again as well.
