I screwed around for a year with an stec 55x and the afs. Don't waste your t=
ime. You will have headaches and be disappointed. Rob will even tell you the=
 stec works with limited functionality and only has had a few partial succes=
ses. It's not a sales ploy. Stec tech support tried to help but have almost z=
ero knowledge of afs equipment.  Also the interface for operation will be a p=
ain. I ended up putting in the afs pilot and should have from the start. Too=
k about 2 days to install.=20
I had the stec in the plane when I bought it. And tried to make it work with=
 the afs. FAIL.=20
