Hi Paul, If the extension doesn't have directions,...so there should be no proplem about that..
"GDPR is a huge area" ...thats true. Oh yes, and it's hardly possible to understand everything on the quick.
I read this here in a blog about GDPR:
"I regard the embedding of Google Maps in a website as questionable under data protection law, as a so-called NID cookie is stored on the user's computer:
According to Google's own information, this is not only used to save preferred settings for Google search (such as language and Google SafeSearch filters), but also to customize ads in Google products such as Google Search.
Additionally loaded by embedding Google Fonts and establishing various other connections to Google servers in the background, through which IP addresses and other data, such as browser and operating system, are transmitted to Google. However, this is to be expected in the case of a connection to a third party service.
However, Google still seems to be working on making Google Maps DSGVO-compliant"

Anyway, I think that Openstreetmap is an important alternative.
