the radio in my car has a problem with the display,sometimes it works, sometimes it is dim, sometimes no display at all, i read this is a common problem in ford explorer radios. I also read this problem can be repaired without replacing any parts but my son lost my info. before I could read the whole repair process on how to repair this problem. I was reading something about soldering, can you give me any info. on the completion of this repair. thanks for your time[/b]
