Interesting stock head unit behavior

[Overdrive]

First time this has ever happened, it only lasted maybe 20-30 seconds (through the time the splash screen and disclaimer screen usually take to clear themselves, and a few seoncds into automatically connecting to my phone and playing music), and everything went back to normal just after I took the picture. It didn't happen again a few minutes later after a quick stop when I restarted the car. We all know the head unit usually boots with the brand splash screen and the legalise warning screen, but this morning this white screen happened. It was a fairly unpleasant 19 degrees this morning, and ice crystals were on every piece of glass but the rearview mirror, but I've started the car on colder days and not had this happen before so maybe it was temp related, maybe not.

Could just be a fluke thing and never happen again, but I figured I'd better get proof of it and see if anyone else has had a similar thing happen to them. I suppose if it happens again I'll try to see if there's any common thing going on and follow up on here.
