Question

We live in a Rural setting just outside of Saskatoon, Sask, Canada. Intersection are marked as [an Example Township 382 Range Road 3043-A]. Is there something that has to be loaded in order work for Rural settings? I haven't been able to find anyone that can enter an address like that for rural seaches. Even those that have GPS system don't find this one very user friendly
