Uconnect 5 - I miss the one click on my 2021, but on the applications page (one click) you can put the camera widget on that page then second click for camera.
It seems somewhere that I saw a video of some guy replacing his temp icon on the screen with the camera icon on uconnect5, but I can't find it again. He just did a drag and drop saying the temp was on his dash so he would rather have the camera on the screen vs a redundant temp. I tried, no go... He said on that video you could do it with those icons at the top... He must have lived on a different plane of reality and I stumbled across it.
