I have to say it isn't user friendly. I can create routes, but have been unable to get them on to the sat nav. The pane that appears to instruct me to log on to MyDrive doesn't work - I know its not my problem 'cos I can log on separately. I can put in email and password, but it doesn't recognise them.
I then discovered MyRoute-app - but it appears I only get that is I upgrade, and I'm not prepared to do that as I've no idea if it'll all work for me when I do.
All very disappointing,I really liked Tyre, but the replacement so far hasn't lived up to my hopes.
