I bought my wife a Garmin Nuvi 360 GPS and she's been really happy with it, navigating around Boston and environs.
But it is so small and light (4"x3"x1", 5 ounces) and has such a great screen that it would be spectacular as a bike GPS. Except there's no mount. The RAM motorcycle mount is mighty bulky, and about $40.
Anyone cobble something together? Setting something up with the stock suction cup mount is possible but there must be a more elegant solution.
