JVC Car stereo - kd-s6060 has gone mad....

[redm]

Hi there, can any of you help? My kd-s6060 car stereo has lost the plot completely. The display shows that it thinks that it has a CD loaded but it doesn't, and it won't allow me to either eject the non-existent one or put a new one in. I think I need to reset it (maybe?) but have lost the manual and not sure how to do it. Any help appreciated!
