Rails: how to change a marker and add infowindow in Gmaps4rails

Question

I'm using the Gmaps4rails gem and this is the setup I have:

def show
    @items = Item.find(params[:id])
    @hash = Gmaps4rails.build_markers(@items) do |item, marker|
      marker.lat item.latitude
      marker.lng item.longitude
      marker.picture({
                     :url => "http://maps.google.com/mapfiles/arrow.png",
                     :width   => 32,
                     :height  => 32
                 })
    end
    append_cur_location
  end

def append_cur_location
    @hash << { :lat=>action[0], :lng=>action[1]}
end

def action
  @lat_lng = cookies[:lat_lng].split("|")
end

I'm getting the current location from the action method and the item location from the item.latitude and item.longitude.

views/items/show.html.erb

<div style='width: 800px;'>
  <div id="map" style='width: 800px; height: 400px;'></div>
</div>

<script>
    handler = Gmaps.build('Google');
    handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){
        markers = handler.addMarkers(<%=raw @hash.to_json %>);
        handler.bounds.extendWith(markers);
        handler.fitMapToBounds();
    });
</script>

With the above setup I got the map to show the current location and the item location. Also, I was able to change the item location marker. But I cant figure out how to change the current location marker and add the info box to the item location. Any ideas how to implement these changes?

INFOWINDOW

you can use marker.infowindow

def show
  @items = Item.find(params[:id])
  @hash = Gmaps4rails.build_markers(@items) do |item, marker|
    marker.lat item.latitude
    marker.lng item.longitude
    marker.picture({
                   :url => "http://maps.google.com/mapfiles/arrow.png",
                   :width   => 32,
                   :height  => 32
               })

    #INFOWINDOW
    # Use can use partial to render infowindow
    # marker.infowindow render_to_string(:partial => 'items/info_page')
    # or else
    marker.infowindow "ITEM HERE!!!!"

  end
  append_cur_location
end

DIFFERENT IMAGE FOR CURRENT LOCATION

def append_cur_location
  @hash << { 
  :lat=>action[0], 
  :lng=>action[1],
  :picture=> {
      :url=> "http://people.mozilla.com/~faaborg/files/shiretoko/firefoxIcon/firefox-32.png",
      :width=>  32,
      :height=> 32
    }
  }
end
