I am using the code below to show the marker for each location saved in MySQL database.

I'd now like to be able to extend the functionality of the page a little further by adding a sidebar, whereby if the user clicks on the location in the sidebar it highlights the selection with a yellow background and then pans the map to the center it on the associated marker where it opens up the info window. If the user should click on the marker, I would like the info window to open and the associated location on the sidebar to be highlighted, again, with a yellow background.
I have been researching this for sometime and I found the exact type of sidebar that I would like here http://econym.org.uk/gmap/example_map2c.html but the problem is, is that this is in v2 of the Google maps API.
I just wondered whether it would be at all possible that someone could please show me what I need to do to get this to work.
