I have a Garmin Quest, without any maps, only towns and cities. I think it is more fun that way. I mounted it to the center part of the handlebars, angles just right so it isn't in the way of any gauges. If I have a certain destination, some town, I do a search for it, and the unit maps the town. I then set it where it shows a straight line from where I am to the correct town. Then I know to follow that general direction and eventually I'll get there.
The benefit of doing this is that I'm not afraid to take some backroads that look fun but I don't know where they go. I still have the adventure of getting lost too.
I also live in the fingerlakes in NY, where almost every road is a backroad...
