I have tried this and have got it to work ok on a 4.1.5 BES server and a 8310 running 4.2.2. Same settings as posted above. It has seemed to update ok. Only shows the latest results though. It is not easy to tell which user it is for though as it only shows as as a userconfigid number which doesnt seem to relate to anything else. Tried the coordinates that it gave and they were correct.
