Premium Sound ate my CDs

[SSVPom]

Well, the cars 2nd (fitted 2003) Premium Sound 6-stacker has become hungry and eaten 5 CDs...

Tried to eject some yesterday and it threw a wobbly, and continued 'whirring' as if it was trying to find the CDs, leading me to have to pull the fuse on it.

Popped the fuse back in tonight to give it another go, and the whirring continued for 10 secs then stopped, and once I had typed the code in, the radio is working fine, but the unit does not recognise the fact it has 5 CDs in in, as the little CD symbols are all blank on the screen !

An no - I'm not interested in replacing it, just a) getting my CD's back and b) some way of fixing it cheaply.

It's had a little hissy fit before and spat CDs out when switching from radio to CD, accepted 2 CD's in the same tray when loading and to cap it all off sometimes when you turn it on, the subwoofer 'pops' and does not come on, leaving me with Prestige Sound, instead of Premium.

Any ideas guys and girls ?
