var request = {
origin: msv,
destination: mgw,

directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK)
{
directionsDisplay.setDirections(response);
directionsDisplay.setMap(map);

else
{
alert("Directions Request from " + start.toUrlValue(6) + " to " + end.toUrlValue(6) + " failed: " + status);
}

how to remove bound marker ("B" marker) on destination? I expect there is only one marker in destination

Answer 1

You need to remove all the markers (with the {suppressMarkers:true} option on the DirectionsRenderer (they can't be suppressed separately)
var directionsDisplay = new google.maps.DirectionsRenderer({
suppressMarkers: true
});
To make the "A" Marker appear, create it:
var markerA = new google.maps.Marker({
map: map,
position: msv,
label: {
text: "A",
color: "white"
}
})

var msv = new google.maps.LatLng(-7.760722, 110.408761);
var mgw = new google.maps.LatLng(marker.position.lat(), marker.position.lng());
// add "A" marker
var markerA = new google.maps.Marker({
map: map,
position: msv,
label: {
text: "A",
