Download the speedcam file and put the file into folder: "iGO/content/speedcam/(*.txt)"
Here is the example with source of UK-speedcameras (about 6000 positions):
But iGO can not find and delete duplicate positions of new added speedcameras.

So, you must locate speedcam(.txt) file of your country ("speedcam_GB.txt" ?) and delete it. On next step you may delete the file "speedcam.spdb" - the database file of all speedcameras. iGO will recreate/update this own database file on the new start-up. Now put the new downloaded "speedcam.txt" file (you can rename the file to "speedcam_UK_2016.txt" as example) into folder "/speedcam/" and restart iGO.
They are now perhaps some additional cameras in the current database iGO that are missing from the current data files (*.txt).
But this is unlikely.
