It has not yet been a year since i bought this unit, since then i have rarely used it, as i have another system and the ipod i bought it for got lost soon after i got the system. Last night was the first time in months that i decided to use it. I wanted to play a cd throughout the night, yet when i awoke at 5 in the morning, it had mysteriously stopped. I decided to try again tonight, but i didn't get that far. it only played half of the first track of the cd, then stop once again. I tried switching out the cd with others, switching between functions, turning it off then on, and un-plugging it then plugging it back in. nothing works.
