Try pressing the reset button on the back or the side of the TND. If it still will not power on contact Rand McNally support. Be sure to have your serial number handy, (back of TND, bottom right)

Download TND DOCK from randmcnally.com. Your User manual explains how to install it. Though it does auto install when you plug the TND500 into a usb port.
