Changing the logo in the sticky menu of a single page

Hi, everybody!
I wanted to know if it is possible to replace the main logo with a different logo on a single page.

On the file functions I put this and it works correctly!

add_filter( 'generate_logo', 'tu_change_logo', 'generate_navigation_logo' );
function tu_change_logo( $logo )
{
if ( is_page( 67 ) ) :
return 'url media';
endif;

// Return the default logo otherwise
return $logo;
}

I'm missing one last step :)
How do I replace the logo on the sticky menu?

Thanks for your answer
Stefano
