Good work but there is an easyer way --- while u sit on chair and u look on TV and are ABLE to choose MP or Sp (dont choose) hold spacebar --- u should stand up then turn left and u will see a small computer -- press f( USE KEY) and type this : 3ARC UNLOCK (with big letters)
Then press esc and press space ( to sit down again) ... now u have all maps ....
Press thanks if i helped!
