I don't know about the two you specified or Canada.

I do know about a $175 portable Bluetooth unit from IOGear in the US.  The
map CD does include Canada.  Based on the functionality, I like it, but the
software has crashed a few times.  Of course, I am a computer programmer, so
I have a ton of software installed on my machine which could very easy have
caused some conflicts.  Based on the Bluetooth connectivity, included
extras, size, and battery longevity, I love it.

This model talks via the laptop and I would not have it any other way.  If I
get confused at a complicated intersection, I can look at the screen, but
other than that, I keep my eyes on the road and listen to the directions.

Check it out their models on IOGear's website.

Bring a laptop car power adaptor and make sure your laptop is not set to
auto-suspend.
