That's a neat trick. Any idea if you can add Motorcycling mode to a Nuvi 500\550 which is essentially the same as a Zumo 220? When I updated the Nuvi 500\550 it added scootering mode. My reasoning is to see if I can get the motorcycling modes fuel gauge added to my Nuvi, that would be really great. Oddly enough, the scootering mode on the zumo does NOT have the fuel gauge, nor the rest of the extra info as when it is in motorcycling mode.
