Bought this unit just before driving from Ann Arbor, MI to Tucson, AZ. Seemed just the thing to play some of the 5GB of my napsterized collection, with their car kit and all. It worked fine for the first day, then one MP3-CD was not recognized. Soon it would only play regular CD's.Called Philips support line and was told they would send a pre-paid RMA shiping label. They did that and the next thing I know I receive a replacement unit, THE NEXT EXPANIUM MODEL EXP-503/17 with MP3 file readout and all. This model has been advertized at Best Buy for $...I'll certainly consider Philips the next time I'm looking for electronics, they have excellent customer relations. Something hard to find these days.
