Hi
Simple: You don't. :smartass:
The Δ is not there to show the route to your waypoint.
The little house is, OTOH.
But, there is (currently) a bug sometimes (something to do with the "heading 0" or 360, a maths problem I guess), where the "house" can make you do almost a full circle to take your heading, instead of doing just a nice turn.
While waiting for a fix about this, best is to check with the HSI (that's good practice anyway).
