The installer at major bigbox electronics retailer installed the head unit today. Overall, the interface seems much better than the factory nav. Siri works well, and the iPhone CarPlay is waaaay better than the factory iPod interface or Bluetooth. I have a few CarPlay-compatible apps (e.g. Downcast for for podcasts) and those work without needing to unlock the screen. I'm not sure about Apple Maps as I normally use Waze, but it's almost infinitely superior to the factory nav in any case. I swear, I tried the voice recognition on it once way back in the day, and then when I got the Aha 'upgrade' (which was also crap), and it was still terrible.
Oddly, I was informed that I apparently had SiriusXM service on the factory radio car, and I know I never paid them for it. That was weird: I never used it, and I checked my credit cards and can't find anything indicating that I was being billed for anything. I did do the SiriusXM class-action settlement, but I literally never used the service.
I have a few minor quibbles with the install, but I think I'll get used to most of them.
The AUX is now disabled, but I never used this anyway. The USB port in the console storage also doesn't work, and he couldn't/didn't wire it in: Instead, there's a small cord end in that storage location. no big deal.
The angle of the screen is now completely vertical, and the screen is inset significantly. I don't know if there are any dash kits that would fix this, but I'm skeptical that they would even exist.
There's now a small microphone at the roofline of the A pillar. I was hoping that the factory microphone in the ceiling would have been used, but I didn't ask on that as I didn't notice until after I left. I'll follow-up about that.
