You did unzip it first didn't you? In any case, that's the original Version 0.03 w/o the map signature patch. It will work for this topo in 1xxx series and most others but not in many new devices. Download the new version 0.03+MagSigPatch from [Only registered and activated users can see links. ] of the gimunlock thread. It will unlock all maps capable of being used in your 1490. Apart from being slow, FIU is resource hungry and may not work for many CNs and other newer Topo maps.
