Just returned from driving in Alberta and luckily the hire firm gave me a car with Incar Nav.
My TomTom with the Canadian map despite running from a SD card, was slow. As the route map and instructions were behind, meaning I passed the turning before being told or shown. Although on the main transcontinental highway was not a problem as turnings are every 20 miles etc, but in City it was slow in comparison to the car nav system.
Would this be due to the now outdated model I have or some other issue.
