I too am having problems with my 97 es300 cd changer. I get the error code 1. Specifically "err 1". I have done an exhaustive search on the web and at pioneer and found that they DO NOT list what this code means. Anyone with information please post.
Thank you.
The previous owner noted that I should spray some compressed air in their and clear the laser lens. I've shot a lot of air in there all over and it almost started to work.
I also just missed on on Ebay that sold for $175 USD. I wasn't about to buy that one with out investigating this error.
I may just have to buy a new unit - I want to go to a mp3 compatible unit sooner or later.
