How can I implement the backend Google Maps location form and map, for front end?

Hi

I would like to use the google maps backend location form and map, to fill a custom field for the creation of a new marketpress product.

I already have the front end form. Just need to add an address bar.

I am extensively using wpmudev google maps plugin, so instead of using a different plugin to get the product location, I am hoping to use the same code.

Any ideas on where to start?

Many thanks,

Johnny
