I have a Sony Xplod CDX-F5500. For the past 4 years I have found Verbitm CD's the best to burn my mp3 files using Nero. They have been playing well until recently a lot of skipping etc. Tried to used a cd lens cleaner, worked a few times but that's it. Now it doesn't play MP3 CD's at all! Not even my old ones. Error and spits it out! It now only plays SOME audio CD's. HAs the laser on the stero gone? But why would it play some audios but not mp3 cd's at all? (just ordered a maxell automotive cd laser lens cleaner (dry), not available in uk, getting it from USA, hope it works)?. :(
