GPS anyone ? Thoughts ? preferences?

[emptysea]

Ok, so this may have been asked and answered I this thread or elsewhere, but do GPS devices exist that allow the user to pre-program a turn-by-turn route of their choice? I'm not interested in "avoid highways" or "curvy roads" features. Rather, I want the device to guide me on the route I plotted out the night before. Maybe they all do this now, but the last time I looked into it, I couldn't find a device that did this.
