Hey folks, I have a just purchased 2001 outback legacy wagon L.L. Bean edition. It has the am/fm radio with cassette and six cd changer on the bottom of the head unit. Radio will not work. I have disconnected the battery and pumped the brakes to reset ecm. Radio buttons will light up with parking light on and the cd player will load and eject cds. Whats my next step to try? Is there any other things link to having a disconnected or dead battery that i need to do? Thanks in advance!
