Thanks for the reply. Overall I am VERY dissapointed with the navigation feature of the Nyon. It keeps trying to take me down paths/tracks that just don't exist or are unsuitable for bike travel. It does not accept postcodes. When I punch in a route, I always select fast (as opposed to eMTB or Scenic. The other features of the unit seem fine. However, I bought my Nyon fundamentally for the navigation feature.
