Radio performance

I've really got a lot of good info and advice from the Forums. I have a Impala SS that the radio pulls in an AM station that is located approximately 90 miles away. It is a CD only radio. The radio in my '96 Roadie wagon is a CD/tape radio and I cannot pull in that station and my local stations are bothered by overhead power lines. Is there something I can check and/or adjust in this radio to improve its reception? Thanks, Ken

To add to my previous request, I've seen an "Err" message on my radio. What's That? Thanks, Ken
