Nagigator 

When a friend or spouse is supposed to help you with directions but, instead, constantly makes negative comments about your driving.

My wife was the nagigator on our trip to the beach.

nagigator 

When the co-pilot in a car is very annoying in the way in which they give directions.

person in passenger seat: Make a u-turn in 500 feet, and then take a left, and don't speed, you're going way too fast! Didn't you see that sign? Damn, you missed the turn, what's wrong with you?!

driver: Jeez, stop being such a nagigator..

Head Navigator 

A head navigator is somebody that cocks their head when turning a vehicle. Try walking around a corner with your head cocked. It fucking doesn't help, so why the fuck do it while you're driving?

Check out the head navigator making the right turn. Notice the head cocked to the right at 30 degrees. The fucking idiot must figure the centrifugal force of their cocked rock-head will assist with the turn somehow.

He/She: OMG we are doing 80 MPH on the freeway.
Driver: What's wrong with that???
He/She: The speed limit is only 65.
Driver: But everybody is doing the same speed.
He/She: And you're texting somebody.
Driver: Quit being such a nagagator, I know how to drive!

Nagigate

Having someone nag you while giving you directions. Usually while driving. Usually a wife.

We'll be there in a bit, I'm driving and my wife will nagigate the whole way.

My wife thought we were lost and nagigated until we finally parked.

Stop freakin' nagigating, I know where I'm going.
