I put a lot of work into a route. Carefully placing s=shaping points (zooming in and placing on the rd) making sure I'm not placing a point at an intersection. I then compare it (I have Gold) to Tom Tom and Open. I then use Google maps and they are all fairly close.
Yet when I ride I inevitable get a a message that says I am going to "leave the rd" then I pass that point and it then says "proceed to XXXX" (The road I'm on).. all other helpful navigation such as next turn and distance stop. it just says proceed to XXXX rd. I can use the graphic on screen to navigate for some number of miles and then it will start navigating again.
This is really aggravating. Especially after spending so much time trying to make a good route.
I use a Zumo 396 (I just ordered the XT)
Any suggestions what I am doing wrong
