Well... v23 with Clone CD Audio CD multimedia doesn't work

I'll try now the same choosing Data CD...
Arg, I'm getting mad! Could it be my MKIII unit starting to die? I've got a memory problem... but the navi stills works and the Map CD is getting inside without any other pb.
Is there any difference upon the place we are in the world? My car is a french one, so it may be Euro specs and not US specs, any difference? The stange thing is sometime, after the screen saying that there is not map CD in the drive, when I insert my burnt CD, it seems to be goos, a screen displays "Please wait..." and the, the CD ejects ans the screens says "Incorrect CD..." *sic*
Well, I'll try and try lol... and in a few days, I sould receive my MKIV unit bought in eBay.
