When the card is inserted, that camera is supposed to see the card immediately and not see the internal memory.
Make sure that the card is inserted properly:
You insert the end with gold contact pads first and the gold contact pads should be toward the back side of the camera.
To determine if the problem is the card or the camera, you will need to try a different card, that is made by a different manufacturer.
Some inexpensive cameras will not work with all brands of cards.
