i'll eat my words - it is a useful feature. possible to retrofit the feature to a MY 20 Kodiaq RS ?

There is a 'dongle' for Android Auto https://9to5google.com/2021/03/09/aawireless-android-auto-wireless-dongle-shipping/

For Apple carplay, have seen this https://cplay2air.com/?gclid=Cj0KCQjwi7yCBhDJARIsAMWFScNltP6fv7-rJWiq4WOdcU3URWoqJfAGC2iEao0Aqjy3kgKQUsrireMaAnExEALw_wcB

 

Hopefully someone else on this forum might have tried one of these and/or have some more information (like: do they actually work, in a reliable way?)

I use apple CarPlay a lot in my 2921 model for my work mobile. iPhone 8. 
But it’s a bit glitchy. Was working great until the phone updated then it would disconnect every few minutes. But worked fine on a cable. I’ve found by tweaking settings on the phone it seems to have become reliable again. (So far!)

Yes it’s very useful, and even though I hate Apple! 
I would say though, the wireless feature is easy but VERY battery hungry. So for long journeys I have to plug it in anyway!
