private TileMapRenderer tileMapRenderer;
    private TiledMap map;
    private TileAtlas atlas;
    private OrthographicCamera cam;
 

    public Map(){
       // Load the tmx file into map
      map = TiledLoader.createMap(Gdx.files.internal("data/testMap.tmx"));

       // Load the tiles into atlas
      atlas = new TileAtlas(map, Gdx.files.internal("data/"));

       // Create the renderer
      tileMapRenderer = new TileMapRenderer(map, atlas,32, 32, 5, 5);
       
       //initialize
     
       cam = new OrthographicCamera(Gdx.graphics.getWidth(),
            Gdx.graphics.getHeight());
 
      cam.position.set(0, 0, 0);
       
    }
   
    public void render() {
       cam.zoom = 0.3f;
       cam.update();
       
      tileMapRenderer.getProjectionMatrix().set(cam.combined);
 
      Vector3 tmp = new Vector3();
      tmp.set(0, 0, 0);
      cam.unproject(tmp);
     
      tileMapRenderer.render( tmp.x, tmp.y,
            Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
   }

Without reading your code, maybe translate the camera negative half the screen width and height?
camera.translate(Gdx.graphics.getWidth() / -2, Gdx.graphics.getHeight() / -2)

Because you zoom?

cam.zoom = 0.3f;

I use the .render slightly differently:

Parameters:
cam The camera to use
layers The list of layers to draw, 0 being the lowest layer. You will get an IndexOutOfBoundsException if a layer number is too high.

// Background / Foreground Layer
tileMapRenderer.render(this.getCam(), new int[] { 0, 1 });

// Render some other stuff

// TOP LAYER
tileMapRenderer.render(this.getCam(), new int[] { 2 });


Have you properly packaged your map? Generated the packfile etc?
