Any help on how to pre select and set up settings for the AM/FM radio. I've looked and tried everything (obviously not enough) and can't figure out how to do it. This is the only car I've ever had that I can't PRE-SELECT a radio station and then hit a button to lock it into memory. Any step by step assistance would be appreciated. By the way, the idea is to have, say, five stations on AM and five on FM and just hit a button to tune in the pre-selected station. Once again, Thanks!
