I have a carradio/MD player from Sony for more then 5 years now. Lately I have trouble to start it up. When pusching in the disc it waits a little and then I get the message 'blanc disc" and the disc comes out. After a few tries it starts working normally. But since a week no matter what I do or what disc I play, it does not take it anymore. What can i do about this ? Cleaning disc ? If its dead, when can we expect HiMD in a car-radio ?
