This is where cycling and driving "sat navs" usage differs.
As a driver I typically don't give a stuff about the route. I don't drive for fun, I just want to get there. I'm perfectly happy to hand over all navigation to my satnav. Provided I apply a modicum of common sense (like not going down stupid little unsurfaced roads) it will probably not let me down. May not be optimal, but will be good enough, and that's what I want and it's what I get from my car satnav.
As a leisure cyclist I'm very concerned about the route. I want the nicest roads, I want to choose/avoid particular hill climbs. I want to pop into cafes. I don't want the shortest route because that would be to simply stay at home.
The job of a cycling navigation unit is therefore half and half. To provide a decent route, and also to obey the additional whims of the rider. From reading this thread this is where the problems arise. It's a fiddly and complicated business to set up a route with intermediate points, and it's frustrating when rider and GPS disagree over the best route between them. And the quality of mapping data isn't good enough to stop the GPS from occasionally sending you down an unsurfaced mud-path or a quasi-motorway.
Personally I don't trust my bike GPS to do any of this, and so do it all myself beforehand. (And also I enjoy the planning)
