Avidyne Waypoint Sequencing

On our Skyview HDX RV12, I could get the autopilot to under cut a waypoint and turn smoothly onto the next leg.

We have just fitted an IFD440 in our RV7 using a Digitrak autopilot and I am struggling to get it to do the same.

Am I missing something in set up, or won't it do it ?

There is a GPSS steering on/off software switch in the configuration mode. You ma6 check to see that it is turned on
