I want the users of my webpage to be able to see an embedded google map with directions from their location to my address.
The following link correctly gets a users location and get the directions to London Bridge.
www.google.co.uk/maps?saddr=my%20location&daddr=london%20bridge
If I use google to get an embed link for that page the start address becomes static. So the embedded map wouldn't get the users location it would just use mine from when I created it.
Swapping the embed source from google with the above link results in a "could not be found" error.

Attempting to modify the embed code from google also results in a blank world google map.
