The Skywatcher equatorial mounts with the Synscan goto handsets will tell you the hour angle of Polaris once you've performed a star alignment...completely useless for us down here though
Many computerised goto mounts include a polar alignment routine that helps you hone in on it, but I've had a bit of a love-hate relationship with mine
There is software to assist with polar alignment if you plug the mount into a computer.
But at its simplest, a good old drift alignment is going to give you the best shot and doesn't require goto, just motorised RA drive.
