I purchased the Carlinkit wireless activator for my Audi A4 with Factory wired carplay. Basically it is a WiFi to USB adaptor that uses Bluetooth to initiate the wireless CarPlay. I purchased it as the A4 comes with a wireless charging pad, but you still have to plug in for CarPlay. I paid around $126 for it. It does work, with a few caveats. Firstly, the text that initially appears when your phone is connecting is in chinese. Luckily my better half translated it for me. Secondly, the audio is scratchy for the first 10-20 seconds; then it works as you would expect. Also, on the Audi, the dash display shows “unknown“ for the track and artist (but the CarPlay display on the center display works just like wired CarPlay). Lastly, it was a bit of a pain to purchase. I had not used Alibaba to buy anything before, and it really was setup to be a business buying these things in bulk, not a one-off like me.
All-in-all, it was worth it; but I can only verify it working on an Audi (even though they mention other makes & models). Just don’t expect much in the way of good documentation. I was able to talk to the seller through WhatsApp, and they have been good so far with support, firmware, etc., but it is a very manual process.
