run javascript function before jquery function

I'm getting the users location on a mobile device and sending it to a database, I then run a jquery function to plot pointers on a map.

However the map always seems to load before i update the users location meaning that the location is the one that was set previously.

getGeoLocation is the function that updates the database with the correct location, but it only ever runs after the jquery function. can't seem to get around this... how can i make the map load only after the call is made?

<script>
$(document).ready(function(){

    getGeoLocation();

    alert('map');

    var result = JSON.parse('<?php usersWithinRadius(); ?>');

    $('#map').gmap3({
        marker:
        {                   
            values: result,
        },
        map:
        {
          options:
          {
            zoom:12,
            mapTypeControl: false,
            navigationControl: true,
            streetViewControl: false
          }

      }

    });

});   
</script>

And this is the code that the getGeoLocation refers to:

//Initialize geolocation
function getGeoLocation() 
{       

    if(navigator.geolocation) 
    {

        navigator.geolocation.getCurrentPosition(
            recordGeoLocation, 
            geoLocationErrorHandler, {
                enableHighAccuracy: true,
                timeout: 20000,
                maximumAge: 120000
            }
        );

        return true;

    }
    else 
    {

        alert('Geolocation not supported');

        return false;

    }

}

//Map position retrieved successfully
function recordGeoLocation(position) 
{

    var data = new Object();

    data.latitude = position.coords.latitude;
    data.longitude = position.coords.longitude;

    /** Other data
    data.altitude = position.coords.altitude;
    data.accuracy = position.coords.accuracy;
    data.altitudeAccuracy = position.coords.altitudeAccuracy;
    data.heading = position.coords.heading;
    data.speed = position.coords.speed;
    **/

    recordUserGeoLocation(data.latitude, data.longitude);

}

//Send the latitude and longitude to database
function recordUserGeoLocation(latitude, longitude)
{

    var BASE_URL = $('#BASE_URL').val();

    var ajaxURL = BASE_URL + 'ajax/recordUserGeoLocation/';

    $.ajax({
        type: 'POST',
        url: ajaxURL,
        data: { 
            latitude: latitude,
            longitude: longitude
        },
        dataType: 'json',
        success: function(data){

            //The record has been added
            console.log('Recorded location: ' + latitude + ' , ' + longitude);

            alert('Recorded location: ' + latitude + ' , ' + longitude);

        }
    });

}

//Error handler
function geoLocationErrorHandler(err) 
{

    var message;

    switch(err.code) 
    {
        case 0:
            message = 'Unknown error: ' + err.message;
            break;
        case 1:
            message = 'You denied permission to retrieve a position.';
            break;
        case 2:
            message = 'The browser was unable to determine a position: ' + error.message;
            break;
        case 3:
            message = 'The browser timed out before retrieving the position.';
            break;
    }

    alert(message);

}
