OSMDroid Overlays Multiple Static and one Dynamic

Question

In my application, I already have some static overlays on the map, and one dynamic which changes it's place when GPS coords change.

My problem is that, when the GPS coords change, I have to clear the dynamic overlay and create a new one, but when I do that, it clears all the overlays, using:

mapView.getOverlays().clear();

So, I'm trying to find the better way to do it.

Clear all the overlays and then place them again on the map (memory consuming) or can I clear a specific overlay?

Thanks

Edit:

This is the dynamic marker:

@Override
public void onLocationChanged(Location location) {
    Log.d("Location", "onLocationChanged with location " + location.toString());

    mLatitude = (int) (location.getLatitude() * 1E6);
    mLongitude = (int) (location.getLongitude() * 1E6);

    GeoPoint gpt = new GeoPoint(mLatitude,mLongitude);

    markerYou.clear();
    markerYou.add(new OverlayItem(getString(R.string.markerYou), getString(R.string.markerYouDescription), gpt));

    mMyLocationOverlay = new ItemizedIconOverlay<OverlayItem>(markerYou, new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
        @Override
        public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
            Toast.makeText(ShowMap.this, getString(R.string.markerYouDescription), Toast.LENGTH_SHORT).show();
            return true;
        }
        @Override
        public boolean onItemLongPress(final int index, final OverlayItem item) {
            Toast.makeText(ShowMap.this, getString(R.string.markerYouDescription),Toast.LENGTH_SHORT).show();
            return true;
        }
    }, mResourceProxy);

    mapView.getOverlays().clear();
    mapView.getOverlays().add(mMyLocationOverlay);
    mapView.invalidate();

    mapController.setCenter(gpt);
}

This is the function that places the static markers:

public void putPlacesOfInterest(){
    this.dh = new DataHelper(ShowMap.this);
    List<Pontos> list = this.dh.selectAll();
    for(Pontos p : list){
        markerPlaces.add(new OverlayItem(p.getName().toString(), p.getName().toString(), new GeoPoint(p.getLat(), p.getLng())));
    }
    mMyLocationOverlay = new ItemizedIconOverlay<OverlayItem>(markerPlaces, new OnItemGestureListener<OverlayItem>() {

        @Override
        public boolean onItemLongPress(int index, OverlayItem item) {
            Toast.makeText(ShowMap.this, "Item " + item.mTitle, Toast.LENGTH_LONG).show();
            return true;
        }

        @Override
        public boolean onItemSingleTapUp(int index, OverlayItem item) {
            Toast.makeText(ShowMap.this, "Item " + item.mTitle, Toast.LENGTH_LONG).show();
            return true;
        }

    }, mResourceProxy);

    mapView.getOverlays().add(mMyLocationOverlay);
    mapView.invalidate();
}
