Using the main control knob to do everything is kind of a pain, The remote control that comes with it makes everything pie. It doesn't have a ton of buttons so its easy to memorize the buttons and not have to look at em while driving.
I don't really listen to the radio that much, so I don't really use presets...but from what I remember its just a few button presses to get to your presets.
