Query: Buy a parachute for Europe

Try getting your money back after it fails. A dark screen after loading the SD card. Called Garmin, placed on hold for 20 minutes, was told that it doesn't work unless the unit picks up the satellites in Europe. So, who do you call with a dark screen in downtown Strausbourg and won't be home until the return date has lapsed? AMAZINGLY, I was also told that the software has no maps (that cost another $300). This Travel Guide is nothing more than a glorified electronic tour book that you can pick up for $20 in hardcopy and with real maps! They call this dumming up.
