Hi, original software was 59.00.545. So I did update to 74.00.324, with "factory" USB module, update finished OK. After I dismantled the plastics etc, and switch USB module to new "chinese" USB module. Now I see on Menu AndroidAuto/CarPlay. But these all the time gray. I connected iPhone, tried Android Samsung too, booth works with other cars. And here is menu still still grey, not active. Tried few cables (cables works in other cars too..). Still gray. Phone is charged, got the message on the display that USB2 is conected, but nothing more. Have someone idea? Yes, is possibility that the module is defected, but before I will send back, maybe is only some my mistake?
