Screen is amazingly clear and easy to read, even for its size. Everyone said the same thing when I first bought the RB-1, as it was still in its box: "That screen is small, no way will you be able to read it"
Amazingly, that all changed to "holy crap this thing is easy to see and use" by every person who has tried it, including the ones who were against it from the start.
The screen choice was very good. It is Active Matrix, like new laptop screens. Not Dual Scan, as used in some units and older style laptops- you know, the ones that loose contrast and change colors when viewed from different angles. The screen is VERY bright, and has an anti-reflective coating for ease of viewing during the day, even with the top down. Brightness can be adjusted to many levels by use of the same knob on the steering colomn that adjusts gauge brightness.
At the push of a button and turn of a knob, you can view great detail at 1/8 mile, all the way to almost the entire country. Also uses "Smart Typing" when entering street & city names, it skips over the letters of places that dont exist in the selected field. Phone Book and Points Of Interest always come in handy on trips.
(I am assuming Active Matrix and Dual Scan are still acceptable terms for these two different types of screens? May have changed to something else by now... but the principles are the same.)
