I have dual 4500 screens.
I will be adding a new Waas GPS, and audio panel, an ARINC and am interested in upgrading my autopilot. Currently I have the Trutrak Digiflight II SV. I would like the new autopilot to:

Be able to track the glide slope, LPV or ILS or both
Communicate with my EFIS in order to command the autopilot from the EFIS screen
Track and fly an internal flight plan from my EFIS

I understand from speaking with TruTrak that the AFS Trutrak autopilot is no longer in production.
Any recommendations please?
