Due to difficulty removing car c.d players it may be an idea to use a cleaning disk as it sounds like it is not reading properly due to the laser assembly.
I would use a dvd cleaning disk (the brushes are usually better) instead of c.d type with a little isopropynol applied to the brushes but only allow to spin for a short time as it will not recognise the disk and spin like the devil.
Disks that are proving difficult to read may result in dalays ejecting.
