I got one for Christmas and wondered if anyone has any experience with this model? It doesn't seem to work with MS Vista so that might be a problem. It also seems as though the map that was loaded on the SD card is out of date. I've poked around on their web site in hopes of finding map updates and possibly Topo maps, but no luck so far. I suppose I'll try to call their tech line and see what options I have. If anyone has any info to share, please do!
