geo location not working with chrome / safari and mobiles / tablets

Hi,
We just installed NW Location Picker that we bought on envato.
We installed it and enabled the geo Location
It works on Firefox and Internet Exlorer as it ask for our location.
We do have an error with Chrome and Safari as it doesn’t ask for geolocation like firefox and internet explorer.
On all browsers one information collected is missing : the town/city in the form.
How can we have this missing field filled in automatically ?
How can we have the geo location taken in consideration on safari and chrome ?
Awaiting your feedback,
Thanks.

PS : Even for registered customers, it generate a “Geocode was not successful for the following reason: ZERO_RESULTS
