Electrical Hum/Buzz from digital dashboard and overhead center stack. Ct4 Blackwing

[Supabash]

Hey guys. Was hoping to get your opinion on a problem I’m having with my ct4 blackwing. I get an electrical hum/buzz from the digital dash whenever it’s on. Sound goes away when screen is off. It’s not coming from the speakers, it’s literally from the gauge cluster. When pinpointing the sound also noticed the overhead center stack also has a buzz, but that turns off when the car isn’t in mid ignition mode, like when all the lights and computers come on but car is still off. I’ve taken this to the dealer who say everything is fine. I doubt it’s anything serious, perhaps just a bad connection somewhere. It’s also not noticeable when the sound system is on or during aggressive driving. But on calm Sunday mornings when just driving around quietly….Incredibly annoying. Any ideas on what I should do or try? Thanks

Same issue. Also 4BW.

On top of that, I had the screen glitch out entirely yesterday; carplay started skipping around songs and flipping through apps like a juke box, then the screen went black on the next drive two hours later. If I hit the physical home button, the screen would illuminate, then when I hit a button on the touchscreen, it would go off again.

I'm going in for the tail lights soon (condensation I posted about), so I'm planning to ask then.

Hoping the sw just needs an update. Anyone else experienced this?

I haven’t noticed this in my 4BW
