Wireless Car Play

Hi everybody, I got my new Tarraco yesterday. Moderyear 21 (re- import from Slovakia). Now I tried to set up Car Play wireless all day. But it just doesn’t work. With original Apple charging cable everything works fine. But as soon as I pull it off nothing is going on. I already have half the internet through, but I just can’t explain why it’s not possible. It’s supposed to be wireless with the new tarracos after all? as? Hardware? Wrong software? I don’t know. I’ve already tested another cell phone. But also without success. Can one of you give me any good advice? Thanks ??
