In what seems to me to be a very odd UI glitch, if I hold down the L/R buttons for what seems to be the requisite amount of time, it often just tunes to the next frequency. That is, up or down 0.2 MHz. I've found that it helps to just press the button and hold it down until it finds the next station. It'll stop at all of them. The button does not seem to repeat for this function.
