I made the mistake of not bringing a CD with me to test the CD changer. It had no CD's in it, but I clicked over to CD on the radio anyway and it showed ERR2. For all I know that could mean no dics, but I can't find a list of error codes anywhere (Lexus forms included). Car is an '01 ES300 with the glove box mounted 6 disc. Does anyone have an owner's manual that lists the error codes or know where I can find a list? I would just go back and check to see if a CD plays, but it's a 40 minute drive, I have to go to work, and the salesman is calling me back for a deposit in a few hours.
