not sure about gpsfiledepot.com but I have a buddy who uses files from http://www.openstreetmap.org/ with his 705 and says they work well; says "if it's on google maps it's on these". my refurb just came in yesterday so I haven't had time to try any of them out for myself yet....not sure if you lose any functionality (turn by turn, etc) by not using the Garmin brand ones.
