Looking for an Overview Map dijit that show extent of big map on a fix baselayer

As a part of the Dutch government we have to comply to certain standards set for showing development plans. One of those standards requires us to show on a mini map the extent of the area you are zoomed into, on a map that shows the complete city map.

Those anybody know if this already exists? I tried changing the existing OverviewMap dijit but my knowledge of the DOJO Framework and ArcGIS Javascript API isn't good enough to get it working.

Try the sample at http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/widget_overviewmap.html - does this help?

Sorry, but no this isn't what we are looking for. In this example the zoom extent (gray rectangle) is a fixed size and the map is zoomed in just like the main map. We are looking for a fixed map layer and an extent that resizes depending on the zoom level of the main map.

The idea on this thread might help you: http://forums.arcgis.com/threads/34623-Multiple-layers-in-Overvew-Map-dijit?highlight=overview. you could create second small map as your overview map by adding a feature layer(from the map service on your first map) as you fixed map layer. Those two maps can essily be synchronized by first map's onExtentChange event.
