I found a site yesterday that looks to be a good source of POI data for the Garmin. You can visit it here: www.Poi-factory.com. Specifically, I was trying to find a data base containing Minnesota lakes and they had a CSV file for the entire US. Cool! They also a bunch of other POI data bases as well: parks, islands, paintball, and beaches to name a few.
Does anyone reading this have any similar sites they'd like to share? Personally, I'd like to find a good source for restaurant POIs.
