Narrative:

Advanced RNAV in a glass cockpit. We have become computer programmers -- which means 'garbage in, garbage out.' our clearance included a bearing and distance from gfs VOR in order to circumnav a restr area. During cruise the 'navigation' mode was set for RNAV only direct from gfs to tnp. However, a waypoint of gfs 185/051 was entered after tnp, not before. Not noticing the error in sequence we let the computer fly the course without backing up the course with VOR/DME data. Approaching the restr area, center rerted us to avoid the airspace. No incursion was made, however a wake up call is in order for all 'high tech' cockpits.
