Mostly? What kind of issues have you had with it? I'll be honest, I'm about to put this in mine and I know I'm going to get frustrated with the lack of wireless capabilities with it very quickly... I hate having my iPhone plugged in all the time, it's not good for it to continuously charge it like that.
Mine is the
Carlinkit 2.0 (Amazon currently has it on sale for $104) on
custom firmware. Only three main issues I've encountered in ~6 months of usage:
1. The next/previous buttons on the steering wheel work only to advance or go back a track; they cannot be held down to seek forward or backwards within a track (this is persistent behavior, unfortunately, though you can accomplish track seeking by tapping and holding the next/previous buttons on the screen itself.)
2. For audio playback, there is some lag (about 600 ms) between a command (like skipping a song) and the audio beginning/changing. My understanding is this lag is present in factory-installed wireless CarPlay also so may not be unique to the adapter.
3. Occasionally voice control audio (like turn-by-turn navigation directions) will be muted on startup; unplugging and replugging the adapter resolves this (intermittent; happens maybe 1 in every 10 times I start the car.)
Battery drain is noticeably higher when using wireless CarPlay (not unique to the adapter) so for trips > 1 hr. I usually still plug in. Overall though, for a hundred-ish bucks it's a pretty solid solution considering how complex/costly MIB retrofits are, not to mention how much more a new 2021 would have been over my 2019. Just my 2¢ of course; not perfect but better than plugging in each and every time I sit in the car.
