Yes, the Colorado has turn by turn with Topo Canada, which is great and it also shows all the roads and labels them most times (the labeling thing i think is an issue since it will show one time and not the other). It tells me when my next turn comes up with big arrows, tells me the lanes i need to be in, and beeps.
But i think you may be right that i missed something somewhere in my commands Night Stalker. I think i may have missed doing that re-route command. I tried looking for that command now but i don't see where it is. There is an option for "Detour" on the main menu when a route is active, but i'm not sure if that's it? I'll have to try it.
When i start, it tries to u-turn me back to the start and then once i go at least a 1/4 of the way it finally figures i'm going in the right direction but keeps trying to exit me at each highway exit. Once i'm on the correct exit from the highway it wants me to turn at side streets which are not the fastest way since you have to go a slower speed. It's almost like the Colorado has no idea about relating speed to a type of road (i.e. side street and highway speed), or i have done something wrong.
My route that i chose was the Calgary airport to 54 Ave SE. Mapsource on my computer routed it from the Airport on to Deerfoot Trail (the Highway) down to Peigan and over to 54 Ave SE. But my Colorado wanted to take the side streets all the way staying closest to the centre line between the two points I was traveling from and to.
