In my clients campaign I use a smart link for get directions. they click it and are taken to the golf groups landing page which contains a google map. if the person wants directions to the golf club they then have to click the directions link which if on mobile device launches google maps app

i think it would be cool if i could have a link in my emails which when clicked looks at group fields then takes them straight into google maps and starts giving them directions to the golf club from current location.
