Not sure what you are looking for. If you just want to convert your wired CarPlay system to wireless then just about all of them work well. They seem to be in the $40 range. Purchased this for my wife’s Mercedes which had wired CarPlay and now it’s wireless. Works great!
In my Lexus I installed a BeatSonic CarPlay adapter which allows a car which did NOT have CarPlay to use it. Works great as well, but about $700!
