A) Work out where the point is on Google Maps and click the point (or maybe very close by).
B) In the box at the bottom, it will display details, including (in grey numbers) the lat/lon address as D.DDD (degrees.decimals). I got '40.689356, -74.044517'
C) In Google Contacts, edit a contact and create a new address (maybe 'other' and called 'GPS') and type '@' followed by the Google Maps lat/lon
It should now look like say '@40.689356, -74.044517'
D) Save the contact
E) Click on GPS address and open in Navigator, and 'Add to My Places' or view it or whatever you want
