Read the source, Luke. Yeah and this is useless, as for most POI noone can read the information - even though it exists. Maybe it even breaks some indexes or makes the search work slower. > If you want to put other information into it you'd have to expand the > code in POIRecord.java.

But for POI that don't have "contact information" the "fix my address" is added, but complete waste of space, as neither the GPS nor Mapsource/Basecamp will read it. It's like making non routable lines routable - there is simply no sense in doing it, as the GPS won't read it. Hence we increase map size without any benefit. It's like adding 200 pages Chinese Characters to the back of a telephone book. Only 1°% of people will ever read it. Hence you waste resources. (just go into Mapsource or your GPS and try to see for which POI there is a popup, you'll notice that for most there is none (exclude cities/shopping and the few listed).
