True that. So after my CPLAY2air died and Autobox arrived DOA, I'm very satisfied with my Carlinkit 3.0.
For what it's worth, I came across this blogger that
tested 15 popular adapters pretty rigorously. He liked certain things about the Carlinkit 3.0 Mini and 3.0 enough to rate them on top of his list, but there are many tradeoffs between these devices (e.g. boot times, WiFi speeds, range, and lag are all over the place).
One thing seems apparent when looking at his test results: our factory UConnect system must be pretty quick to launch CarPlay. My "ignition-on-to-CarPlay-launch" times (even with the old CPLAY2air adapter) have been much faster than the blogger reported in his testing.
