Hi,
please specify your request!
e.g. the radar plugin has nothing to do with the radar on the bing map (if you want to have a radar on that map)!
if you want to enable the radar in the Bing Map, add <radar visible="true" /> inside the <layer> element of the Bing map (see the vtourskin.xml).
an example for how-to use the radar plugin with an custom image map, is the
scenes-with-imagemap example (included in the viewer download package),
best regards,
Klaus
