Google Maps - german directions

Hi, support team,

I'm currently working on a huge German project and I want to include your Google Maps plugin. How can I adjust its language to German. Interesting that it does not follow the overall Wordpress language which is set to German as some other plugins obviously do. I also need to make sure that the translation is done only once (if I need to do it) and that I don't have to repeat it after every update. Thanks.
