Step 2: Harness Connections & Model Revisions
The Roadnavier universal harness includes combined connections for both 2004–2006 and 2007–2008 revisions:
📅 2004–2006 Models Notes
Use the 5-pin + 14-pin adapter connections. Ensure the factory AC controller connector is securely plugged into the matching CANBus pass-through socket.
📅 2007–2008 Type-S / Base Notes
The factory Blue Plug may require a tiny plastic alignment tab notch shaved off using a razor blade for a snug latch. Do not force the plug.
Step 3: Aftermarket Backup Camera Wiring
-
Video Signal: Connect yellow RCA cable to
CAM-IN. - Camera Power ① (Red Wire): Splice to the positive (+) 12V reverse tail light wire in the trunk.
- Ground Cable ② (Black Wire): Connect to a solid metal ground bolt inside the trunk.
- Reverse Trigger Wire ③ (Red Wire): Splice directly into Pin #3 (BACK) on the main 16-pin head unit power connector.
Step 4: CAN-Bus Protocol Settings (AC & Steering Wheel Controls)
While Roadnavier screens are pre-configured before shipping, a factory reset or power interruption might clear the CAN-Bus memory. If your climate control touches or steering wheel buttons do not work after installation, simply re-select the correct protocol in the factory settings. The factory settings password is 3368.
