Front sensors and camera display coming on

[DarkSky20]

Noticed something new today, when driving, my front sensor alert have activated my front camera on the radio. I haven’t touched anything in settings. My last update on my radio shows Sept 2020 when I bought it. Was sitting in a left turn lane and the front camera came on, one car drove by on my right but it didn’t return to the Sirius xm channel screen until I made a left turn

Mine does this too.  May be ice accumulating on one of the front sensors.  That or road grime.

That’s what it was. Ice. Thanks

Mine does this EVERY TIME I wash it when it's below freezing.  It has also happened when it is super cold (-40 without windchill) and the exhaust from the vehicle in front just hangs there. (exhaust fog)
