Motorcycling with the Go App for Android
1) Using the My Drive desktop app, one can plan a route, can now avoid motorways as one of the criteria, but also choose a level of 'Thrill' and also have the app display 'scenic' roads to help with ones choice. No need to always go Fastest as prescribed by Google Maps and others.
2) Syncing this route with other devices allows the user to access the route using the GO app on their phone, but the best bit is that if you use 'Serena' as the voice and check the correct settings, 'she' will read out the road names and so you can just slip the phone into your pocket and use a pair of earbuds. Eyes on the road the whole time! Instructions are clear and often have lane instructions in plenty of time.
3) You can share routes that you've made by exporting a GPX file from MyDrive. Friends can then go into MyDrive on their PC and log in then select MyRoutes they then have an option to import a GPX file. Once they have done that and checked the option for it to Sync to their Units then they will have it in MyRoutes on their TT units.
You have the same option on your account to import .GPX files created on various sources.
I must credit YamFazMan and DougLap for most of the above advice, I've just put it together in the hope its as useful to someone else as it was to me. Thanks both.
