A friend just told me that her '01 Sonata's CD player has quit working. It will read track 1 and you push play and it will display Er6 and reject the CD. She bought the car at a local Toyota dealership which is no longer here. One local electronics shop said flat out they won't work on it and recommended another, who won't return her call, so they obviously don't want to do it either. She's tried many CD's and a cleaner, nothing changes anything. Are independent shops unlikely to work on these? The nearest Hyundai shop is over an hour away. Or does anyone know any tricks that might jump start the thing into working again? Is Er6 just a generic code or does it actually indicate something specific?
