Good Morning- A couple of symptoms , when turning the radio/cassette on, the word CODE appears BUT the C in CODE is blinking on and off.. Is that a sign of something wrong? I then enter the code as found in the owners manual :11221, and then click OK. the only thing that changes is the first numeral 1 is now also blinking on and off. What gives? If I cant figure this out, what other radios were offered for this model and is there one that has in in dash CD [player? Thanks for your help, Paul
