You know, I have read several posts related to this topic, and it makes me wonder. I have the stock HU and I play burned CDs all the time. My discs are of at least ten different brands (I carry over 100 in the car) and all of them work perfectly. Some of them are even 99 minute CDs. I burn them at almost any speed, some of them even at 32X, with no problems. Now I do have problems getting the disc to load or come out, but that has nothing to do with the CDs as it does this to the original CDs too. I wonder if Ford used different suppliers for their CD players or something. Anyone have any information?
