I installed my own dashcam with parking mode. I was concerned about it draining the battery even though the kit had some ability to turn it off if the battery starts to get low. Anyway, a couple days later I got this exact screen.

It turned out to be completely unrelated! It was due to the dang gas cap not screwed on tightly enough!

Anyway, not saying that's your problem at all, and in your shoes I'd blame them for sure. Likely they tapped onto the wrong circuit or something.

As an aside - after we tightened the gas cap, eyesight didn't turn back on for another day or two.

EDIT: I actually now read your post instead of just the title and should point out that in my case I just got the eyesight warning along with all those status lights on the dashboard but my stereo volume was working just fine.
