If you are using a calculated route ("Turn guidance on"), you will get turn annoucements at 0.1 mile to 500 feet before the turn. You need to use a "good quality" track route for the calculated routing to work well (and make sure "recalculate" is off).
You will also see a big white arrow on the map on the turn well-before you get to the turn.
I have only ever used ride with gps generated TCX files -- dunno if that is high enough quality. I've seen the white arrows. I guess I need to sit down with the unit and play with the settings some more. The more I use it, the more comfortable I am with it. I have to say that it has never gotten me lost and it has tried to keep me from riding bonus miles -- which I ignored. It does say that I'm off course a little more than I would like. The course we are talking about has a lot of hills and trees, so that probably contributes somewhat to the spurious off course messages. They don't usually come at a point where they matter. The big problems I had were all involving keeping it charged. I have some nice little liion batteries now that do a great job of keeping it charged
I will always carry a cue sheet. I wasn't using it on the fleche, which caused a little friction with other team members who were when one of my calculations was off due to an excel error on my part.
