DavemcRC350

Hi, I’m hoping that someone can help me figure out why I have to turn the stereo on every time I start my 2021 RC 350 F Sport when using a memory stick in the USB port (which is what I listen to all of my music on)? My previous 2018 RC 300 would return to the same screen the car was in when it was turned off but my 2021 needs to have the audio turned on every time, select usb and then set my home screen. It only seems to do this with the USB, if I have the radio on when I turn the car off it returns to exactly the screen that was on when I turned the car off. I have read through the manual and searched online but cannot find any information on this anywhere. I’m not sure if I’m missing something or if there is a glitch in the system. Everything else seems to function as it should, it just doesn’t return to the USB when the car is started up again. Any help that you can give me would be much appreciated. Thanks a lot!
