The Garmin database for IFR airports with only a textual ODP; or vector SID with an ODP indicated by the 'T'; uses the word 'none'; when the departure for that airport is selected by the pilot. Thus; a pilot who has not done prior departure planning to discover the presence of an ODP could be lulled into believing that no departure exists and thus not fly the ODP; and contact terrain during the departure. Garmin could just as well publish the letters ODP as the word 'none' to alert the pilot to seek the ODP in other publications/means.
GA pilot reported that when a textual OPD or vector SID (T) is selected using the Garmin Database; the word 'none' is displayed; which may mislead or allude to the lack of an obstruction departure procedure.
