"That's not a glitch, it's a feature!"
Couple things I noticed about the center stack, and one about the rearview camera mirror.
The display is generally nice, the adaptation for light/dark, especially with the ambient lighting, is nice. I'm used to, and generally prefer a driver oriented *very* basic info setup, so this is....something different. The huge geek factor is mostly for your navigator, imho, while you keep your damned eyes on the road. I don't really want to see all those pleasing graphics while I'm driving. Looking forward to playing with the settings more, but for now, I hope my AWD Bolt SS (there I go again) will have a minimal, driver focused setting, along with its sport suspension, better tires, and Recaros.
There was a software glitch moments after driving it out of the showroom. Backing it out of the tire bay after the winter tire install, the backup camera didn't come on, no birds eye view, and the center stack screen was frozen. (Mostly I was pissed I couldn't turn on the seat heater, it was damned cold.) Didn't seem to be anything I could do to cancel a screen, etc. Huh.. Moments later while driving, the center screen auto rebooted. Haven't heard that reported elsewhere, and hopefully it'll be an isolated occurrence. I'm sure it's Version 1.0, or something close to it.
Noting this event with the dealer, I asked about updates to the software, and per my service rep, these will come over the air via Onstar, regardless if you've purchased a data plan, for the first 3 years. (Unclear what happens after that, but hopefully they'll have ironed out the software by then.)
In case you're in the dark as I and my salesman were, on the premier you activate or turn off the rearview camera mirror with the same tab that you would usually darken the mirror with. It's a pretty bright, good resolution image, but for me, if you leave it on, it has the effect of looking backward on a train....nauseating. And all those things now behind you clicking along in your upper right field of vision are somewhat distracting, imho. I'll probably leave it off until I want it for backing up. Otherwise it's just like a little TV screen staring at you playing what's behind you while you're trying to focus on what's in front of you. The setting I'd like to choose, Chevy, is for it to come on when I'm in Reverse, and off when I'm in Drive (well, Low).
