Create Audible Time Checks and Reminders for Full-Screen Navigator
As most experienced Streets and Trips users know, it can be a little difficult to keep track of the time of a planned route while you are using Full-Screen navigation. This can be especially true on long, featureless journeys. However, there is a way to do it. And this way, you do not have to fiddle with Streets & Trips to get back to the Driving Directions and then back again to Navigation mode.
Plan your route in the usual fashion and then add Stops along the way on the route approximating when you would like a time check, taking care to assure that these new stops are truly on the route. Then, look at the Driving Directions, noting the arrival time of each of the stops. Next, rename (right-click on the Stop in the Route Planner to access the drop-down menu to find Rename) the respective stops with the time, say, "Time Check: 1:04 PM". If you want to be real anal about it, you can move the stops so that they are exactly on the nearest hour. Then as you drive along, you can compare what Microsoft Anna (or Sam) says about the time of your route plan versus what your watch or dashboard clock says.
See, for example, the attached map and route for driving from Regina, SK, to Calgary, AB. Say that you want to arrive in the downtown at 5:00 PM, having set the route speed options all to the max. I have set up time-check Stops along the way to call out the time on the hour. In this way, the driver knows how he/she is doing against the original route plan without ever leaving Full-Screen Navigation mode.
Also, you can insert helpful reminders as Stops to call out, for instance, "Remember to fill up in Medicine Hat" or that you are in a new time zone.
