I intended to use this radio while jogging, but that's just about impossible. First of all, unlike Sony's older molder that simply had up/down bottons for moving through the pre-set stations, this unit uses a separate button for each station. It's very difficult to select a station without stopping and looking at the unit. The buttons aren't even arranged well so that you could just feel around for them, just look at the picture. In addition to the five buttons for the preset stations, there are 4 or 5 more bottons, all the same size, that can be accidently pressed as well. In short, navigating stations while jogging is about impossible. Too make matters worse, the volume dial is easily bumped, and very sensitive. So, while jogging along, trying to change stations, you're likely to blast your ears out accidently.
