Hi all,

I have this problem where out of no where my DEH P5500MP headunit is unable to read CDRWs giving an error-11 message on the display. It was playing them fine before. Now it can only read CD-Rs

Steps taken to check:
- ensured discs were "closed"
- tried different CDRWs
- cleaned headunit contacts.
- reset player by disconnecting it overnight.

The only thing i could really remember is that i am now using newer version of nero to burn CDRWs than before and i cant get the older version back to test. I have also tried other burning softwares with no success.

So any pioneer users experienced this problem? or any way to overcome this problem?

Thanks in advance.

try burning at lower speed ... previously i use higher speed .. the my DEH 6850MP giving the same error.. then i use low speed to burn.. everything seems fine

Thanks but tried it and still same problem. hmmmm im at a dead end now. Dunno whats wrong with it. havent tried using a cleaner to clean the lens but its reading cd-r fine so im not sure if thats the problem.

i thought its normal tht it doesnt read CD-RW? my previous pioneer had this kind of problem but last i checked on the manuals... it really doesnt read CD-RW... only CD-R

His pioneer is higher end 5500MP la. CD-RW should be read. U got try other disc? May be ur RW reburn too many times alr.haha..

craziechild - It does read cdrws. It read them like a dream before just lately it stopped.

tplcaik - tried new disc already. Imation and brandless.

I asked a friend that also has a pioneer and he told me he had the same problem burning discs on his new computer but when he goes back to his old computer and burns there it plays.

Hmmmm could it really be the version of nero thats is the cause? coz i install a new version of nero just because i came across the disc but the burner drive remained the same. Got to find an older nero disc now

Maybe the HU len near gone lo..

But besides the cdrw, other is working fine right? I think not related to his lens.U should try to burn from other cd rom as well.

Ok just tried with a few months old Pioneer DVD writer, selected lowest speed, imation disc erased not more than 5 times.

Problem still occurs lol.

I think i should just give up on CDRWs and just continue using those few sen CD-Rs.

Thanks all for the comments.

then software problem on your computer might be the cause...

Yes it might be a software "nero" update that causes the problem. Maybe this older pioneer players need specific type of burning for it to recognize CDRWs.
