How do I extract the coordinates from the response content in navigation

extract them from what? A list of lat,lon perhaps? 3.10066, 101.72550 (an item in a list of lat,long) in Malaysia can become separated into lat 3.10066 and lon 101.72550

What you do to separate depends on what form the latitude and longitude are in and what you intend to do with them when you get them. There are many other ways you can separate the latitude and longitude.
