I use IGO8 on mine and that's really about all you need. For planning routes, I use MS Streets & Trips then GPSBabel to convert .est files to .kml (which is what IGO8 uses). But you could just plan your routes on Google Maps and download the .kml. The unit looks like a disk drive. Routes go in the IGO8\CONTENT\USERDATA\ROUTE folder (you may have to create one when hooked up to the USB port.) With IGO8, you have to set the screen size in the sys.text file to screen_x=480, screen_y=272. It's found in the IGO8 route directory.
