I wanted any suggestions about a decent radio am/fm cd player to replace my work truck factory am/fm radio. This is in a 2004 GMC Sierra 4x4. I will probably keep the truck a few more years and wanted to improve radio capability. I don't own an Ipod or similar device or know much about that but have a number of CD's . I just turned 60, so please understand my ignorance about the present formats. I see from a brief look at some that many have an input jack for an Ipod or phone- not sure how that works. Thank you!
