GPS format input


On the website if you enter a GPS co-coordinator in a different format that DD, the site does nothing and the location is not changes.

Maybe an error message or the site could convert other formats to what the site uses?

Our Garmin GPS gives us:-
S36.85733° E174.52081°

And we need to convert to this for it to work on the location field.
