Have you updated your maps, and do you have coverage for Canada?
I just updated my older Novi maps and it is quite good. The new North America maps are large. Require an 8 gig SD card for all of the data. You have the option to load only regions into the GPS.
I have a 2014 Ford with Nav. It's maps are good but only as good as the base mapping used. I've seen errors in both Canada and the US. Often this is in new areas where houses and streets did not match original development plans.
Depending where you travel you may want to do frequent map updates.
