After what seemed an eternity my wish has come true.
Finally I have Wireless CarPlay working on my MY20 Eclipse Cross using the Vrriis
Wireless CarPlay Adapter 3.1 I mentioned in my first post.
It should also work on MY19 Eclipse Cross and below too.
I have also tested a BROxiongdi Wireless Adapter and it works too.
Once I updated the adapters to the latest June 2022 Update via 192.168.50.2 the Wireless adapter booted up and the setup Menu (red menu) showed on the Car Display head unit.
My iPhone asked to connect to the adapter via CarPlay and after 30 seconds or so it connected to the Eclipse Cross radio head unit.
I tested it with Phone Calls, Messages, Siri, Music, Steering Wheel Controls and of course Maps & TomTom maps, all working.
Also tested whilst the iPhone is Wirelessly Charging, Wireless CarPlay is working.
I now have Wireless CarPlay & Wireless Charging working on an Eclipse Cross.
