Thanks for the thoughts. Where exactly IS the aerial?

I recently bought the update disc, which seems to have installed correctly on my 2007 S-type. However, the system can't find my car's position automatically, and it's impossible to set exactly using manual calibration. When I start driving, the icon moves randomly across the map, into water etc. Is some kind of receptor not functioning? Any help much appreciated.

My 2007 s-type produces a long continuous note on reversing. Does this mean a sensor has gone, or something else ?
