The Nuvi 255W also has the ability to view JPEG files. This comes very handy together with Google’s Panoramio if you plan your trip ahead of time. You can set your GPS unit to navigate you to the points where the photos are taken. You can even send addresses to the unit from Google Maps or Mapquest. In addition, there is an optional MSN Direct Connect to feed you the web favorites, local events and news headlines.
As is the standard with all GPS units, the Garmin Nuvi 255W has an auto re-route function (recalculate the route to your destination if you happen to go off calculated route), route avoidance (such as highways and tolls), choice of route (fastest, shortest, eco, etc.) and the ability to receive traffic alerts. However if you have more than one waypoint on the way, it does not show the most direct route. It was a surprise for me, because this is just an additional simple calculation that the device could make. I wonder why Garmin did not offer this feature. Plus, I would very much like to have a car locator feature.
As with the competition in the GPS arena, manufacturers are making the mp3 and audio book reading standard in their budget lines. These features are not found in Nuvi 255W. Also XM Navtraffic and Radio for U.S. are not supported.
