I am a volunteer and trustee at a country house open to the public. It's in an isolated location though correctly indicated on Google & Bing maps. But when visitors put the postcode into their satnavs they get lost. We need the satnav to take them to the car park. Can anyone help please?
Postcode is GL10 3TS
Coords for car park are 51.711N 2.298W
Thank you
