I have a brittian autopilot.  cant remember the model number now.  It has cap and trk and theres a switch in my panel to switch between nav1 and nav2 which are currently kns80 and k 155. Can it take a signal from a 430 or 650?  How about with a G5 HSI? sort of thinking of putting some waas nav in the plane and just wondered if that was a possiblility.  Ive never even tested the cap and trk connected to my current radios but did have the brittian unit overhaul a few months ago.
