As of V4.40 fw 55/56/65/66 can again use unlocked maps [prob. not NTU]: [Only registered and activated users can see links. ].

Use only [Only registered and activated users can see links. ] to unlock, original gimgunlock won't work to fully unlock maps with some modern units/some firmwares.

SOLUTION FOR PROTECTED FIRMWARE
