When I use either the TomTom or Here map your route is ok. The picture below is the TomTom map (in black) showing the standard OpenStreet map route in blue. There is obviously a problem with the OpenStreet map and because it is open source data, there isn't much that MRA can do. You could choose to have a gold account and all of the benefits that a gold account offers. You can have a free All In One trial for 14 days that includes MRA Navigation too.
You haven't said which navigation device that you will be using? If you download the .gpx 1.1 files for this route and add them to a TomTom, it should follow the track of the picture below.
