I've got a Garmin Dakota 20 in the snap-in cradle for the RAM mount, off the handlebars. It has full topo maps & touch screen.
A mate with a Zumo (and no topographical maps, as standard) has no screen indication of his small country road to his property. The roads on screen for him only start when back on the main road.
I find the Dakota/topo maps invaluable for checking that the track I'm on is the correct one -- sometimes, at a gravel road intersection, the correct road isn't immediately obvious.
If you get authentic topo maps, then the GPS can route you to a chosen point/home etc -- as a regular GPS does. Though, not having spoken instructions, you have to look at the screen, rather than getting the instruction through a headphone etc.
It's when following a route already set that it's clear I am on the correct track -- as that is marked with a thicker (green) line, compared to the other roads around
It does have compass and GPS vehicle speed etc.
With this sort of GPS (rather than a car type unit), it is possible to set up a route in advance in a town by town and/or intersection and/or map grid reference manner -- as a named route. Whereas, most car type units can just have one alteration from the chosen route -- and with no ability to set-up a number of routes in advance in the unit's memory.
I don't know it a bike specific GPS can pre-set a number of routes.
Also -- the batteries in the Dakota last easily a whole day -- and are AA's, so replacements are everywhere. It can take re-chargeable batteries -- which re-charge if you plug the unit into a socket on the bike (or car etc), or take a small recharge unit for a power outlet for the motel eg.
Small car units that talk to you are cheap enough to buy and have in, eg a tank bag -- to navigate through a city etc.
I couldn't go where I do with the current peace of mind without a GPS unit with topo maps in.
The Dakota is good for paperless geocaching too, if that interests you.
