Anywhere to get a single file of all POI in the US? Years ago I had a crappy GPS, but it had 12 million POI. I now have a Magellan 4350 with 6M or so. I'd like to load all POI I can find. I don't care if its a 1-2 gb file since I can add more memory. Seems like a good idea to add all Walmart, gas, Sams club, etc.
