RTMedia in menu

I have RTMedia installed in my application, but I’m not able to add the link MEDIA menu in TopNavMenu. I don’t have this option.
To add RTMedia in TopNavMenu I wrote a code(bellow) to the functions’ child file.
My questions are:
1 – How add the menu from buddypress interface menu configuration(apparency->menu)?
2 – How could I insert a fontello icon to the ‘Media’ Menu link?
/***************************************************************************/
function my_wp_get_nav_menu_items( $items, $menu, $args ){
if ( is_user_logged_in() && class_exists( ‘RTMedia’ ) ) {
$user_id = get_current_user_id(); // get current logged in user id
$url = trailingslashit ( get_rtmedia_user_link ( get_current_user_id () ) ) . RTMEDIA_MEDIA_SLUG . ‘/’; // get user’s media link

// add new menu item to nav menu
$new_item = new stdClass;
$new_item->menu_item_parent = 0;
$new_item->url = $url;
$new_item->title = ‘My Media’;
$new_item->menu_order = count( $items ) + 1;
$items[] = $new_item;
}
return $items;
}

add_filter( ‘wp_get_nav_menu_items’, ‘my_wp_get_nav_menu_items’, 99, 3 );
