Moin, got today the GPS receiver for my D3100. Very fast delivery. Along with the product obtained is also the link for the German manual to get it to download as a PDF. After connecting the GPS, the camera displays the same on the display by a flashing GPS sysmbol that recognized the recipient and the search for satellites running. After about 30 seconds a valid position signal has already been determined and symbol in the camera, and the red LED indicator on the GPS went on permanent display.
Then several pictures taken with about 12 meters distance from each other. Then load the photos to your computer and view with Google Picasa, the position can be on the map. The positions were more than determined exactly with perhaps 1 meter difference !!! The GPS-E determines the coordinates, altitude and time from the GPS signal. The compass display is "misused" for Anzhal the satellite found.
Power consumption with the new MTK chipset is yet to be seen.
