I got my tuner a little while back in fear that they wouldn't exist anymore by the time I got a decent radio station in my area.

I noticed, though, that there doesn't seem to be any way to just wander through the dial. If I tap the left and right buttons, it hops to the next preset. If I hold them down, it scans to the next tunable station. The knob just changes the volume. And nothing on the remote seems to do the job, either. So how do I get from 88.1 to 88.3 without typing it in on the remote (which, by the way, is oh-so-easy when opening the sunroof, talking on the cell phone, worrying about the computer meltdown at the office, and shifting into sixth gear)?
