The display uses Blanview technology which increases visibility in direct sunlight whilst reducing power consumption (details can be found here Blanview ).
Precise
A combination of a great display with the best maps. The unit has a large internal memory to store multiple maps form the worlds main cartographic publishers. Beyond road maps a user can download topographic maps which when combined with a relief map provides the user with a stunning 3D landscape to help understand the terrain ahead.
