My truck has a nice feature that I wish my car did. On the steering wheel there are two buttons for going up/down through the presets, which there are six pages of, and can be mixed AM/FM/XM. It has a third button which will go to the next station on whichever band you're in. So if I'm on XM 2, I can tap it to go to 3, 4, 5, etc. On the long drives to my dad's I'll usually start at the bottom and work my way up I hit the kids/sports stations, then start over.
Might seem lazy, but a lot easier than reaching across the dash to get to the knob on the radio. I wish the car would allow mixed band presets and the channel button.
