A couple of weeks ago, based on some positive forum mentions, I got a new Wireless CarPlay adapter (it does Android Auto as well): the 2024 Sunweyer. It's not magic, but at $36 from Amazon, it's much cheaper and so far decidedly better than my previous adapter (CarLinkIt). In my 2017 Subaru Impreza, this has had noticeably faster and more consistent connections once I start the car. Too early to be confident about the reliability, but I hope it holds up, because I'm much happier with it.
