Got an eTrek, which I have downloaded all VORs, NBDs, VRPs, intersections, etc., very useful if you're looking for a new VRP for the first time....but more importantly on my way home from the airport, put it in Map mode, zoom in to < 1 mile, and download my list of 500 speed camera's which some kind soul decided to post on the internet, and hey presto, no speeding ticket
Cheers
EA
