i have the 3.0 Carlin and it works very well. Audio is great and no lag. Very occasionally on long trips, it gets hot and even has to be reset (unplugged and plugged in). It's rare, but it happens. still 100% worth it and way better than hardwired. I also added a wireless charging pad in the armrest and it plugs into carlin. That's probably why it gets hot. now thinking out loud.
