The older HU, didn't recognize them unless they were CDR and where burned at 4x or lower speeds. You can burn them at low speeds and make them work, or buy a new HU, and burn them at 52x and play audio and mp3 CDR and CDRW. Like everyone else with new HU. Also use CDs that look as close to normal CDs as possible, they are the fastest and easiest for the laser to read.
