This evening, BlackBerry Maps has received an update on BlackBerry 10. The new update doesn't bring a change log with it, unfortunately, so odds are it's just minor bug fixes. Make sure you check for the new v10.0.0.634 of BlackBerry Maps in BlackBerry World's My World tab. Click Refresh and you should see the update. Otherwise, hit the link below to be redirected to it from your Z10.
