Something is definitely not ok with that tile. I've seen this behavior (only POI's but no roads) before, but I haven't been able to understand why that happened. Can you post the tile number (73240xxx.img) which shows only POI's and post the download URL? Here's the download URL (requested ~1509 UTC on April 10), for a single tile: http://planetosm.oxilion.nl/~lambertus/garmin/routable/02-04-2009/d9635902e7... tile is: 73240299.img I looked up the bounding box: 73240299: 1966080,-3362816 to 1990656,-3330048 # : 42.187500,-72.158203 to 42.714844,-71.455078 which seems entirely reasonable and covers my town. -71.5 runs right through town, almost at the police station at 42.4something, so I was definitely looking in the right place. And, when I went too far east the GPS V said it had no map data (the 'mapsource' designation went away and it said 'overzoom'). I made two other requests, and had similar trouble with both of them. Plus the odd behavior where the GPS V claimed not to have maps for the areas that should have been covered. Thanks very much for offering the service and for looking into my problems. (This is really a tiny point, but I first thought the data was from February: "Based on OpenStreetMap data from: 02-04-2009." Just now I realized that's the European date format (or maybe all but US). It would help us Yanks not get confused if you used ISO8601 and had dates like 2009-04-02.)
