NAVBLUE has the procedures as per original message (one for each runway with LNAV and LNAV/VNAV minima). They definitely exist.

From the FOBN:

For APP mode to engage (assuming 2D approach)

a. A flight plan including an RNP approach with horizontal guidance only (LP, LNAV, or LNAV+V) must be active in the FMS
b. The FMS must receive valid SBAS signals
c. The NAV mode must be previously engaged

I think b. is the problem. Have you got GAGAN enabled in System-GPS Status-SBAS?
