I run a simple machines forum and it has a mod (plugin) that uses google maps too - but the way its implemented is much better and more intuitive. But I think that's due to the way the mod is written and google data implemented in that mod - as opposed to the quality of google solutions themselves.
Is there not a XenForo plugin offering that sort of functionality?
