I going through the set up process with a 3500 with the 4500 processor (is this just a 4500?) a VPX pro and Garmin GNS430w. I was successfully able to get the EFIS to recognize the vpx-pro but not the Arinc. In the "about" section no version is stated. I think version 4.0 is needed.

Is this a set up problem or do I need to load this software separately or something else?
