Who is the actual manufacturer for cessna part number 38423-0026? This is a nav/com connector (tray side)?

I tried to google it and could not find an answer for you. Who makes the nav/com unit? Honeywell? Collins? What you need to do is contact the manufacturuer and get an istallation manual or have them give you the technical data associated with the part. They should also be able to supply you with a manufacturer who may have some in stock. Most of these have a common style connector that is used in other applications. Check with Duncan Aviation at Duncanaviation.com and talk to AVPAC sales. They may be able to help you further.
