I have a Garmin Quest. Wouldn't tour without it. It helps us find our motel/hotel/campground when it's 10pm dark and raining. It keeps us on the right track when we are trying to navigate the craziness of large metroploitan areas.
I don't really rely on it for all decisions and judgement, but is always there just in case.

The Quest is waterproof, has an internal battery as well as being able to run on the bike's battery. You can pre-load routes and maps for pretty much any trip you want to take. We use it when we are walking around big cities as well, if we're looking for a specific cafe or store.

I still carry maps with me, and check them over every once in awhile to get an idea of where we actually are in this world, but I've found that the gps is certainly a worthwhile addition to our touring.

And, as my bike only shows speeds in km/hr it is nice to have the mph display on my gps when we travel stateside.
