There is a new update for the QUI application for Nokia N9 from the Nokia Store which includes Google+ sharing option.
“QUI allows you to share via SMS/Email/Facebook/Twitter/Google+ your location to a friend. Use your GPS to get your location and share it by sending a SMS/Email/Facebook/Twitter/Google+. Your friend will receive a link to a web page with your location on a map. GPS and Network access are used as positioning methods. No data is collected. No ads are shown on the application.”
