what is your firmware? surely you have a Linux-based head unit. there is no Variant Coding tab in it

Here are the software and firmeware versions:
CD_20.EUR.55W_L.001.001.221223
CD_20.EUR.02.221208.MICOM
Anyway to have wireless CarPlay in this case? Try to downgrade it ? Or change the headunit is the only solution ?
