For my motorcycles, I’ve had a Garmin Quest and later Quest 2 for years. I loved their small size, long-range battery and that they were water proof. But the time it took to recalculate and ability to lose satellite signal even in light tree cover became unbearable. So I began to seek an upgraded unit.
It came down to the Zumo and Nuvi 550 units because they are water proof, a requirement for my bikes. The Zumo clearly has several features the Nuvi does not, but was lacking in one critical area for me - battery life. The Zumo is rated at 4 hours, virtually requiring hard wiring. Since I use GPS on all my bikes, I did not want to go through the hassle, and the Nuvi comes with an 8 hour battery.
