Your new used radio CD is branded "MG".
From which MG was it extracted? Did you ask the seller?
It should no be very old for you may insert a SD card and even, if I'm right, an USB device. It looks weird.
Don't you have any label at the back of your radio CD or elsewhere at the top or the bottom.
The best bet would be to get a clear and precise identification of that model in order to find out a comprehensive leaflet or user book.
