Seeing your track while routing

When I download a gpx file and use it for routing, it shows the track with thick purple lines.  The problem is that while navigating, I can't hide it, change the color or see my actual track that I am creating.  I can obviously see my location but if there is something directionally, I want to see based on where I've been, I can't find a way to see my tracking.

Any way to see both the route and my tracking?  Or hide the route temporarily?
