When I'm cycling through the sources (Music Box, CD, Compact Flash, etc.) there are three (A, B, C) for AM/FM radio, each with 6 station presets. That's 18 radio presets.....I listen to 4 stations, all on A. I still have to cycle past B and C, as well as Ipod, which I don't use either.

Is there a way to remove those unused Sources from the rotation so I don't have to cycle past them all the time? All the manual says about using the "Source" button on the steering wheel is "If they are not ready to function, those modes will be skipped" but it doesn't skip anything.
