Географическое расположение Google Maps + Geo / SQL

У меня есть сценарий, который отображает кучу адресов в базе данных SQL (все они геокодированы) и помещает их на карту google. Я не могу понять, как иметь центр карты в местоположении пользователя с помощью своего мобильного устройства GPS. У меня есть сценарий, который делает это, но я не могу понять, как объединить две функции. Кто угодно? Пожалуйста, помогите мне, потеряв сон …

Вот мой код:
