In-car GPS units are illegal in Québec.
From Quebec's highway safety code:
439. No person may drive a road vehicle in which a television set or a display screen is so placed that the image broadcast on the screen is directly or indirectly visible to the driver, except in the case of a closed circuit system used by the driver to operate the vehicle, or a system used by a peace officer or the driver of a road vehicle used as an ambulance, in accordance with the Act respecting pre-hospital emergency services (chapter S-6.2), in the performance of their duties.
I suppose one could interpret "a closed circuit system used by the driver to operate the vehicle" as including GPS units.
(I just checked the Texas Transportation Code, and GPS units are specifically legal here. Whew.)
