c150 FM presets?

I recently purchased a refurbished c150 unit online after already owning a m240. If you have a c150 please answer this for me- after setting your fm presets how do you change the preset stations without using option/down button and view all presets menu? On my m240 all you have to do is press the play/pause button to scroll quickly through the presets. My c150 does nothing when the same button is pressed, which kind of defeats the purpose of having presets…

Did I get a defective unit or do all c150’s have this problem?
