I have a VX2 system and recently purchased a previously loved NT C MAP card M#US906LX3.  I inserted the card with the unit powered off, then powered up the unit.  The unit gives it's normal "beep" upon power-up and the screen color changes shades slightly but then does nothing else.  If I remove the card the unit powers up as usual.  If I insert the card with the unit powered up already the unit is completely unresponsive upon the press of any buttons.  I am not very familiar with this unit as I just purchased the boat and any previous plotters I have had utilized pre-loaded charts.  Am I doing something wrong?
