header hook deletes my navigation

Hello!

I want to exchange the text-Logo with my custom image logo on the executive child theme with a header navigation, like in the demo: http://my.studiopress.com/themes/executive/#demo-full

I used this header hook:
http://screencast.com/t/MpmjzLkIuR

BUT it replaces not only the Logo text with my Logo-image,
but also it deletes the header navigation.

If anybody can help me out with the correct hook to use,
(=replace logo text with image, without deleting the header navigation)
that would be great!
🙂
