The Jeppesen navigational data card and the terrain/obstacle card may look the same but they are very different internally. Because of that, they require two card programmers, one for the Jeppesen data card and one for the terrain/obstacle card. The card programmer for the terrain/obstacle card can be purchased at https://buy.garmin.com/shop/shop.do?pID=1190 or by contacting Garmin Aviation Customer Support at http://www.garmin.com/garmin/cms/us/support/supportcontact#fragment-2.
