Struggling with windiness on Rider 410
I used it to drive from Plymouth to Basingstoke, with the least windy route. However, the section to Exeter took nearly 2 hours as it kept putting me on unclassified roads which turned out to be single track with loose gravel and grass growing up the middle. What I was hoping for were mostly B and minor A roads, but whatever I tried it did not want me to use anything apart from unclassified roads. Is there anything I can do to give me better control?
Having had that experience I then tried using my laptop to plan a route very precisely to go on the roads I wanted and then downloaded it to the Rider. The mistake I then made was that while riding the route I changed my mind and took a detour. The route then became useless because it it seemed to want to take me back to where I left the route, rather than re-joining the route at the closest point to where I was. Again was this me not using the device correctly?
