I know that electrical problems show up more in the cold. I will be going to the dealer this week and document the picture at least. I am still 16,000 miles away from being out of warranty, so less than a year for me. I will check to see if it has the update but it doesn't look like software I think. I don't know for sure.thats wild looking...never had that happen. there is a laundry list of issues reported with the radios, some related to cold weather. So it may be normal. Good thing you got a picture though, your dealer will need it to make it a warranty claim for a new one.
Also, there is supposed to be an update of some kind for the radios early 2021...not sure what that entails. May fix your issue as well as some of the other screen issues that happen when using apple/android carplay.
