I had the same “fix” for mine, if I didn’t have the 1/8” jack plugged into aux my screen would jump constantly from input to input. Since taking the console out I have no issues with power to usbs and the media hub is working as it should. Thing is, I didn’t actually do anything, I just took the console out, did a mod (took the cd player out), put the console back in after cleaning the connectors and it all works now. Well, maybe not all, the light under my console lid stopped working. That’s fine, I’d rather have power and CarPlay again. Edit: Do you have a cd player? It’s curious to me that things work now without it.
