Geolocation Header and Zoom Variation

A couple of questions on the geolocation plugin. I've added it to my Item Show page, and it works fine. But I can't seem to track down where the word "Geolocation" is generated as a title for the map, I'd like to change it to something else.

Also, can I control the zoom level on an item page geolocation, separately from the default zoom level for the main map controlled by "Settings?"

Thanks in advance...I'm nearly done with this site, so I'll stop bugging you about it soon enough...
