Review on 2021 Wireless Carplay Adapter: Upgrades OEM Wired CarPlay to Wireless, iOS System Support, for Cars from 2017 to Now (Black) by Pete Door

Works great on my 2021 Kia Telluride, maybe 10 seconds connection delay but it connects every time after initial setup, instructions are not that clear but just plug into USB port . and go to setup phone devices on your iphone 12 pro ios 14.6 then do a bluetooth search on your phone for maybe 5 minutes and you're done, plus it's small enough to hide almost anywhere.
