Sony CDX-F7705X Car CD / MP3 Player

I purchased this unit because I owned a Sony in the past and it was great. The sound from this unit is very good. Unfortunately, the first problem I had with it was that it skipped when playing MP3s. I returned the unit for a new one and the new one had the exact same problem. When I called for customer support, they really couldn't fix the problem. They said the usual. Try different media, try different burning program. I did all that many times and the problem remained. I then stopped playing MP3 and just played CDs. The unit worked OK for a few months and then developed skipping problems along with numerous other problems. Sometimes the unit would give an error message and would stop working for a day or two. Sometimes the unit would skip repeatedly. It seems like the quality control had disappeared from Sony car CDs.
