Hi
I am looking at possible purchase of AirNav. Has anybody experience of operation near my location which is 8 km SW of Heathrow in an urban location, or can anyone suggest how I can check out the signal strength prior to  buying.

You can check out the location of users near you (well at least where their IP may be) with this map.

Signal strength is likely to depend on your location, whether you are at the top of a hill in the clear, or at the base of a valley surrounded by tall buildings.
