Woohoo! This makes me very happy. I ended up ordering the Carlinkit one on Amazon because a reviewer said it worked in their '19. The other forums say that the Carlinkit and Carplay2air dongles are the same so fingers crossed.I received mine today. The king of procrastinators "ME" put off taking a chance and buying one for a few months. I should have done it sooner.
After doing an initial firmware upgrade the dongle just plain works! I love it! For short trips you just get in the van and start her up and the iPhone connects to the van while your phone is in your pocket. For longer trips I will use the wireless charger that I installed in the van a few months ago to keep the battery charged.
No more cables! I'm a happy guy.
Over the next few days I will give the dongle a real workout and I will keep track of battery and data usage.
