I usually listen to 1 MP3 CD loaded with songs, played on random. On occasion I will jump through the stations to see what's playing there as well. Around 4-6 times already I will be listening to a CD song and then the audio will cut out and the system tells me it can't read the disc or that I need to eject the CD. After I eject it and re-insert it, the memory on all of the FM stations will be reset. I'm out of warranty and have learned to live with it but was just wondering if this has happened to anyone else.
How did you check the battery? Did you check it with a load? If so, then it may be a loose 12V connection to the audio unit.
