Those instructions are for the DII VSVG if you have it coupled directly to a GNS-430/530/480/650/750. It is pretty limited in what it will do connected only to one of those units. When connected to the EFIS and in EFIS mode, it will follow the HDG bug, ALT bug, fly VOR/ILS/LOC/GPS approaches, and it will allow it to level at the MINS bug. When you hit SUSP on the GPS, it will auto-sequence to your MAWP and the EFIS course needle will auto-slew to the new course and give you CDI indication. It will also cause the EFIS to stop holding at the MINS bug and change the vertical mode to V:ARM, causing the autopilot to start a climb to the ALT bug which you would have set previously for your first altitude on the missed approach procedure. You can fly an entire approach from Enroute to the Missed Approach without touching anything other than the altitude bug and your throttle.
