Navigation systems for guys?

Guys don't ask for directions, so it would violate the Guys' Code of Ethics for one of us to buy a navigation system for our car. Right?

Not so, says this item, which claims that guys buy the systems precisely because they won't ask for directions. But that's asinine. If you won't ask a human, why would you ask a machine?

Maybe there's a partial answer here: "Despite advertising targeted at women, the big majority of TomTom's customers are men, Goddijn said at the summit in Paris. 'It is still very much a guy thing, but also a bit of a girl thing where the guy buys it for the girl,' he said." I wonder if the guys have to guess her size.
