One of the many changes in the new manual finally lists the Altimatic III, IIIB, Autocontrol III, IIIB-1, IIIC autopilots as allowed to interface with the GAD29B. There are some other changes in as well, such as the single 429 input to the GNS series (as opposed to previous requirements to use both and not being able to interface with the GTX345 at the same time), as well as some changes to the spec'd wiring for CANBUS (no longer MIL-C-27500, now requires CAN24TST120) and the additional requirement of a diode on the power feed to G5 as well as 15 ohm resistors to the CANBUS inputs to the G5s.
