I have a Kenwood KCR X-77 Cassette / Receiver (amongst other components) in my Jap Import Impreza - thing is, there are so many buttons and 'features' on it, that I can't work out how to use it properly - I can't find any info on it on the net - does anyone else know this unit? If so, got any instructions? I can't even work out how to set the damned time on it...
