Bob,
Do you know which radio it is? I have the Clarion. If it's the
Clarion, just go to the station you want, then hold down the preset
button for about 3 seconds. You'll hear the station suddenly go out for
a sec, and come back. Voila! Saved station.
But mine was the basic model. There were I think 2 higher-end radios,
both Alpines?
