What CA said. Moving your seat will tend to either change what part of your butt you're sitting on, or change your knee-over-pedal position, or both. Getting the knee-over-pedal position wrong can give you knee trouble; sitting on your forward soft tissues instead of your aft sit bones is just painful. If what you want is to change your upper body position, you probably want a different stem. Your LBS should be able to help!
ETA: On the Navigator, changing the angle of the stem is an option, but keep in mind that this will change the steering as well.
