Map Not Working On Mobile Devices

Hi,

I’ve found this plugin brilliant but I just discovered that it’s not showing up when the website is viewed on an ipod/itouch, etc.

This is the page in question: http://wanderingon.com/wordpress/index.php/travel-resources/travel-map/
Is there any way to fix this?

Thanks.
