Map all posts on one Google Map

I have played with several plugins but cannot find something to do exactly what I want to do. I would like to make one page with one map on it. This map would have markers that are each post from all categories in the blog that has lat long custom fields. The markers would have a link back to the post. The lat long can be from any other plugin that can add coordinates, I can go back and add them without any problems.

Any idea which plugin can do this or combo of plugins? Thanks!
