Some while ago I was asking about entering favourites in GPS coordinates into the new Sat nav as the instructions dont appear to cover it. After some trial and error I have got a procedure that works for me and in case it is useful to anyone I will outline it below:-
Ignition on/ Press top right Nav button/Navigation/Magnifying and Marker symbol/ Search Box/ Enter Latitude Number-then comma-then space, then Longitude number. If it East then no symbol is nescessary, but if it is West then a minus symbol is required before the Longitude number.
Examples of coordinates which are always required in decimal form:-
(I obtain them from Google Street with option set for decimal degrees).
51.12345, 1.56789 this is for an east location
52.98765, -1.54321 this is for a West location
Then click on the result that appears in the box below
Then click "More"
Then click on yellow star and save as your named choice
When I refer to East and West, it is from the Greenwich meridian which of course is Zero longitude.
Hope that helps someone. The reason I use GPS coordinates a lot is because some times the address is not straight forward and not found, maybe out in a remote part of the country, postcodes arent always accurate enough.
See what you think.
