Deployed in test. Tested in IE7-9, latest Chrome, Safari, FF and on Safari/iOS.

The map gives the user a nice message if the street address doesn't match SBKs POI.

Right now, the address is just clickable, there is no "Show on map" text. Easy to add, now or later (maybe when the known issues below are fixed).

Known SBK issues

• The map itself doesn't adjust the width when the viewport width is changed. Closing and opening the map render the correct width.
• The map isn't touch enabled but you can zoom and pan with the controls.

SBK will notify us when their new map system is released.
