You download the GUI software referenced above, then you plug the white USB stick with a little white cable coming out of it into the back of the copter. Open up the battery compartment, remove the battery, then looking straight into the compartment, on the right hand side will be an opening in the plastic and a set of whires that has a white connector. (This set of wires was velcro'd to the wall of the drone in my unit). Undo that connector, and the usb cable will fit in on one side. Carefully slide the batter back in without breaking the wires. Now turn on the drone and fire up the q500 GUI software, and browse the settings. It isn't hard to find in the software at all.
