After doin' even MORE research, it looks to me that both of you guys are correct... for 2077.2, what I need is the 554 "High" /blue disc.... thanks.... seems like quite a few people, includin' the most of the people sellin' 'em, don't have any idea what they've have - they mostly just say "ask your dealer about compatabily before buying" ...
