Indianapolis service center completed my upgrade today and had it ready around 3pm. Total turnaround time was a little over 24 hours, but I don't think my service center runs after hours (like I've heard some of the busier markets do). No sign of damage from the upgrade, no issues with my glove box opening, none of that. Aside from the 4 hour round trip because the car had to stay overnight, the entire experience was flawless.
My reactions echo pretty much everybody else's, it's significantly snappier, the improved performance of everything going on over on the instrument cluster is really nice (Rainbow Road moves so fast now, and the gradient won't degrade to bars of colors!), especially the scroll wheel options being much more accurate as you roll through them. I had a high endurance SD card and usb reader in the car and ready to go before I dropped it off, so dash cam is already up and running. I have a handful of clips that I plan to post up as an example of the AP2.0 camera quality. I can leave links if people are interested when I get it done, but it's nothing different compared to what
@Akikiki has already put up.
I also echo his sentiment in that it's a $2500 upgrade to improve the quality of something that may or may not be working just fine for you already. Personally, I agree that it is totally worth it. The improved performance of maps is like night and day, the dash cam feature may pay for the upgrade by itself someday if it catches a negative run-in (hopefully not!), etc. I literally NEVER used the FM tuner, so that was a no brainer for me.
Now, if you'll excuse me, I just left my 9 to 5 to go start a new life in Stardew Valley and I need to tend to my parsnips.
