Also valuable to note that threads like these are biased towards those users having issues. For what it's worth, I've had my Carlinkit 2.0 adapter since November 2020 and it works incredibly well. I experience no reboot issues, I'm on the March 2021
@VLud custom firmware, and everything largely works perfectly. There's some lag when skipping tracks but that's present with factory wireless CarPlay as well. The only issues I have off the top of my head are that the steering wheel next/previous buttons don't function as track seeking when held down (only skip) and sometimes I need to unplug/replug to get spoken Waze alerts unmuted (though that might be a Waze bug.) My two cents for whatever it's worth!
