I just bought a Wildview 4.0 from Gander Mtn. and a 256mb card for it. the card is made for the camera or compatible and says that it should hold close to 180 pics in high resolution. but it will only hold 56 then the camera says its full. technical assistance at wildview said they have no idea and that it must be the card. do cards come faulty and should i be able to return it?? or what else could be wrong?
