Summary: The screen is definitely large enough. The maps are a little outdated. It'll cost about $40 to update. Not as many POI's as TomTom or Garmin. Cannot update POI's. Good GPS unit for the money. It'll get you from point A to point B. I would recommend it as long as your looking for a simple unit.
HORIBLE gps. do not buy. get garmin, tomtom, magelian, or mio instead.

Summary: bought 2 of these. owned for 2 yrs now. one after some time did the known issue of the locked screen and in chinese says "unauthorized". it will cost you the price of a new unit to get it fixed unless you bought it from an "authorized" reseller which most on ebay are not. i have found no known fix for this yet. it needs to be reflashed via usb. the maps are WAY out of date. they lag on when to turn and when you are at your destination.
Summary: Overall, this is a great product in terms on functionality vs price. The Copilot version 7 is a average GPS software but its maps are not as accurate and updated compared to most other GPS manufacturers. Version 8 is much better but not available for this unit. I bought this unit strictly for spare parts as my touch screen on my RW400 is not working. Taking it apart, I found it was the flat cable to the touch screen that went bad.
