CD Player Error
 

I have a 'Honda Navigation System' in my CR-V Sport that has decided to continually report that there is a 'Disk Error' when I try to play a music CD, I have tried many many different music CD's but still get the same message. I can succesfully play a £1 cleaning disc that will run and complete which includes stage 9 as a music track. Have checked the format of the cleaning disc which is in a CDA format and of course the music discsare in the usual WAV format. Any ideas guys as have tried just about all I know and there is no reference in the manual to this fault ???
