Current location symbol significantly behind the position from LocationChanged event

Question

Hi,

We are trying to implement navigation in our application (Runtime 200.8.1). We have noticed that current location symbol significantly behind the position from LocationChanged event. Position from LocationChanged event shows real situation where is car at the moment (red dot). The indigo line shows the rest of the route. This prevents the driver from making the right decisions.

I saw another thread with your comment about one second for animation.

I could say that car already passed crossroad, but current location symbol is about 5-10 meters before crossroad on speed 50 km/h. Driver will always miss required crossroad to change direction if look to map. Current location symbol moves like a frog trying to catch real car position: gap, no gap, gap and so on.

On asynchronous LocationChanged event we make redrawing of rest route, checking of speed limit, rerouting needs and etc.

I would like to see at first moved current location symbol then get LocationChanged event (like WYSIWYG). To see real car position is more important thing than others.

When you say significantly, how much are we talking? There is an animation happening on each location update to make the moving smooth, which means it can be up to one second behind, but never more. Are you seeing more delay than this?
