If I run your application with firebug turned on, it returns the error "navToolbar is not defined" (You MUST use Firebug during the development).
Taking a look to the Google Maps extension API reference, I see nothing concerning toolbars, so I believe it works only with the "main" Javascript APIs that includes Dojo (navToolbar is a dijit by esri).
For example, in this days I'm developing a webmap template based on Google Maps and jQuery, I created a toolbar with:
full extent, dragzoom, dragbox (for selection and query), draw polygon (for selection and query), measurement tools. At the moment it does not include navigation history, but it is planned.
Hi digy79,
Yes, I know that Firebug should be a must, but I did not figure out how to use it correctly 😞 Sounds stupid, I know. I will try to find the message you found.
I found a lot of nice examples right here (of course after my thread):

I will post my toolbar here again when I´m ready (Monday 😄 )
