So far the only sat nav I have found that allows me to exactly plan a route is My Maps and then download to Google Maps. I know that some software uses waypoints but they all still route their own way. The reason is I like to explore certain roads/villages/towns and so plan at home on my desktop before setting out. Now I have managed to get my login sorted for Google on the Model 3 I thought I'd got it sorted. I downloaded a route but there is no guidance option on the web browser version of Google Maps so I am still stuck with using my phone. Has anyone any other suggestions for web based sat nav that I might have missed. Many thanks.
