I would like an appliance that would cook my dinner and also clean my house for me.
Seriously, though, if you're looking for something that will map out routes for cycling for you, I think you'd be better off considering a dedicated bike computer/GPS unit. Get a dedicated golf watch for your golf game. About the closest thing I could find was a Garmin Approach S62 watch, but I don't really know how useful it would be cycling (or golfing, for that matter.) Then again, it's the little windmill thing that always messed up my golf game. I could never time the windmill arms right to get the ball through the tunnel.
