BlackBerry Map

It's not possible in Blackberry Map to show custom icon for POI.
Things you can include in Location on Blackberry Map:

• The latitude of the location * 100,000. South is negative.
• The longitude of the location * 100,000. West is negative.
• The label to be displayed beside the location.
• The description displayed when the BlackBerry smartphone user selects
  details.
• Zoom level from 0 to MAX_ZOOM.
• Address
• City
• Province or state
• Country
• Postal code
• Phone
• Fax
• URL
• Email address
• Category
• Rating information between 0 and 5

Using MapField

As an alternative you can try MapField + manager/screen paint override.

Custom extension for MapField:

class CustomMapField extends MapField {
    Bitmap mIcon;
    XYRect mDest;

    public void moveTo(Coordinates coordinates) {
        super.moveTo(coordinates);
        mDest = null;
    }

    protected void paint(Graphics graphics) {
        super.paint(graphics);
        if (null != mIcon) {
            if (null == mDest) {
                XYPoint fieldOut = new XYPoint();
                convertWorldToField(getCoordinates(), fieldOut);
                int imgW = mIcon.getWidth();
                int imgH = mIcon.getHeight();
                mDest = new XYRect(fieldOut.x - imgW / 2, 
                fieldOut.y - imgH, imgW, imgH);
            }
            graphics.drawBitmap(mDest, mIcon, 0, 0);
        }
    }
}

Example of use:

class Scr extends MainScreen {
    CustomMapField mMapField;
    Coordinates mCoordinates;
    public Scr() {
        LocationProvider provider = null;
        Location location = null;
        try {
            provider = LocationProvider.getInstance(null);
        } catch (LocationException e) {
            e.printStackTrace();
        }
        try {
            location = provider.getLocation(-1);
        } catch (LocationException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        mCoordinates = location.getQualifiedCoordinates();
        add(new LabelField("Latitude: "
                + String.valueOf(Coordinates.convert(
                mCoordinates.getLatitude(),
                Coordinates.DD_MM_SS))));
        add(new LabelField("Longitude: "
                + String.valueOf(Coordinates.convert(
                mCoordinates.getLongitude(), 
                Coordinates.DD_MM_SS))));
        mMapField = new CustomMapField();
        mMapField.mIcon = Bitmap.getBitmapResource("poi_icon.png");
        mMapField.moveTo(mCoordinates);
        add(mMapField);
    }
}

Prepare GPS data

If it's real device, be sure GPS is available and turned on.
If it's simulator, then before you start program use simulator menu -> simulate -> GPS Location to set GPS data.
Other option is hardcode your own Coordinats and use them without GPS:

    double latitude = 51.507778;
    double longitude = -0.128056;
    Coordinates mCoordinates = new  Coordinates(latitude, longitude, 0);
