With its big screen, Bluetooth for connecting your phone and live traffic avoidance system, this is a perfect gps device. Lane assist and junction view (with actual display of the signs and where to turn) make it easy to navigate even in central London. 3D view of the roundabouts and junctions ahead also gives you a much better idea of where to drive. One of the most useful features is the lane assist in the top left corner of the screen, giving you enough time to move into the right lane for the upcoming junction.
The only slightly negative aspect is the way some of the functions are enabled, for example traffic avoidance. Nuvi will tell you there is traffic on the planned route by displaying a small red icon on the left side of the screen together with the estimated delay due to traffic in minutes. Selecting the icon gives you another menu, where you have to select traffic and then select avoid, which opens another menu asking you if you wish to avoid the traffic and after confirming, Nuvi will start to recalculate the route.
But overall an extremely useful device with wide screen for even easier navigation.
