For mapcards, you're only choice should be Navionics HotMaps or Navionics Hot Maps Premium both in South Edition. Don't think the Platinum will run in the Elites.

Don't know the specs on the X37 of Maj's, but the X67c is a color unit with built in GPS only a smaller diaginal screen. Not sure if it accepts map cards. In any event, $200 for both is a bang up deal. The X67 is worth that easy.
