Why have you created a SUM-file? They are just check-sum files created by Garmin diagnostic tests. SUM-files are just waste of space and can be deleted.
Generate 25-character unlock keys with JetMouse KG as described two times already in the thread. You have to use your UnitID together with FID=480, PID=31, RgnID=0 and VenID=0. Paste the generated key into "Voice\WallaceGromit.unl". UNL-files are just plain text files with the unl file extension.
