General Motors issued a technical bulletin detailing how hardwired radar detectors and the side-mirror glass aren’t cooperating. This could lead to degraded mirror glass that displays a spider’s web of lines that obscure the reflection on 2020-2022 models.

According to the bulletin, one cause might be an aftermarket radar detector hardwired into the inside rear-view mirror. The detector could cause a higher voltage to go to the side-view mirror, resulting in the unsightly damage. If there is damage, then the radar detector is likely tapped into the inside mirror’s X1 connector, located behind the mirror’s front cover. The fix requires disconnecting the jumper harness and replacing the damaged outside mirror. Sadly, the warranty doesn’t cover any damage caused by aftermarket devices, so owners will have to foot the bill.

The post doesn’t detail the science behind the phenomena, though the Corvette does feature GM’s new digital vehicle platform that gives the model a host of advanced features like over-the-air updates. However, the electrical platform did toss a few hurdles into the C8’s development, delaying the car’s debut by about six months. At the time, rumors pointed to a “major electrical issue” that left the vehicle unable to cope with the necessary electrical load.

I hope this isn't a dupe as I've searched.

I rely on my RD so I hope they get this resolved, if not it may time to move to battery op. I have also seen that there is no good mirror mount point.

Blendmount has a rigid mirror mount for C8. Now if only the wiring issued gets resolved.

Installed a Blendmount for C-8 HTC and a mirror tap for a Escort Max360, no issues
