Routed the intercom cable to test for fit. Tried to install the Navigator and realized it needs to be installed from the rear. Installed the rear bracket/connectors to the navigator tray. Removed both the panel and subpanel to install the navigator tray. The rear tray angle mount was installed on the wrong side of the subpanel, so those rivets will have to be drilled out and reinstalled on the correct side. Lots of connectors and cables between the ACM and the rear of the PFD.
