GPS routes not lining up with roads

[cloudgazer]

A few weeks back on a ride to botrivier I noticed that my GPS kept displaying that i was not actually on the road, but just off it, following the same route.

This week I was plotting a ride I'd like to take - and noticed the same thing the GPS route does not follow the road.
Its as if it's not lining up correctly.

Any advice?
