Ho do I change the language in the Google Maps Plugin?

Hi there...

How do I change the language in the Google Maps Plugin? I want the direction and everything to be displayed in german. There must be a simple way to do that, like when the plugin gets it's information from google it should be possible to just ask for different information, right?
which file would I have to edit to achieve this?

If anyone has a quick fix for that, please, post it. I have to show the website to a client today, in like 4h, and this is the only thing not working correctly.

Thanks in advance,
Silvio
