Whew! Finally, i have the debug values for the button presses. Sorry it took so long, I came down with the crud and have been feeling pretty bad.
Interestingly, I had ctrl-c from the player to get this to work. When I used 'q', the tuner would power off and I would never get the serial dump. Here goes:
seek up 02 00 4c 4c
seek dn 02 00 5b 5b
preset 02 01 4c 4d
am/fm 02 00 af af
