Create a navigation worksheet to place in your first dashboard that contains a calculated field using the formula
"Click here for X"
-- or whatever you would like the text to state (if nothing simply use "", or try the shape of an arrow)
Set up an action on the dashboard that when you click on the navigation worksheet within the current dashboard it takes you to another dashboard or sheet. The action would be a filter action that you would run on select and "Show all values". Set the target sheet to be the other dashboard or sheet. Since your Navigation sheet has no data that needs to be passed on, nothing will be filtered in the target location.
Hope this helps,
