Before proceeding, you must confirm your hardware compatibility. Firmware version 6.xx is strictly for CAN-bus systems and be used on VAN-bus systems (which use version 5.xx). Check Hardware

: Locate the button under the leftmost rotary dial. If it says

, you have a CAN-bus unit. (If it says "RDS," you have a VAN-bus unit and should not use this guide). Verify Software : Hold the button until the extended menu appears, then select DEVICE DESCRIPTION to see your current version (e.g., 6.51). 2. Preparation : Use a high-quality blank CD-R. : Use software like or Nero. Burn the ISO at the slowest possible speed (1x or 2x) to prevent read errors.

: Ensure the car battery is fully charged. It is highly recommended to keep the engine running

during the entire process to prevent the car from entering "Economy Mode," which would abort the update and likely brick the unit. 3. Installation Steps Start the Engine

: Keep the car stationary and do not turn off the engine or touch any controls during the process. Insert Disc

: Remove any SIM cards and navigation discs, then insert the update CD. Confirm Update rt3 upgrade 651 na 663 build 890 can42 new

Before starting, ensure you have the following ready to prevent a system "brick" (permanent failure):

Power Stability: Keep the engine running throughout the entire process to prevent the car from entering "Economy Mode," which will cut power and corrupt the installation.

Media: A high-quality blank CD-R. If burning your own, use the lowest possible speed (e.g., 2x or 4x) to ensure the older RT3 lens can read it without errors.

Software Files: The extracted folder typically contains "CD" and "USB" subfolders; most users burn the "CD" contents directly to an ISO image. Step-by-Step Installation Guide

Language Check: The system may default to French after the update. You can change this back to your preferred language in the "Configuration" menu. RT3 Upgrade 6.51 Na 6.63 Build 890 CAN.42 - Facebook

The fluorescent lights of the garage flickered as Elias connected the heavy diagnostic cable to the port. On his monitor, the status line blinked a cold, expectant white: RT3 UPGRADE 651 NA 663.

This wasn't just a routine firmware patch. This was the "Ghost in the Machine" update. For months, the custom CAN-bus community had whispered about Build 890, a rumored firmware stack that unlocked the raw, unfiltered telemetry of the car's nervous system.

"You sure about this?" Jax asked, leaning against a stack of tires, his eyes tracking the scrolling green code. "That CAN42 NEW protocol is experimental. If the handshake fails, you aren't just bricking the head unit—you're freezing the whole drivetrain."

Elias didn't look up. "The standard 651 build throttles the intake sensors. It’s like the car is breathing through a straw. 663 opens the lungs." He hit Enter.

The dashboard of the vintage sedan went dark. A heavy silence filled the garage, broken only by the hum of the cooling fans. Then, the center console glowed a deep, neon violet.

INITIALIZING BOOTSTRAP...APPLYING PATCH: RT3-651 -> 663KERNEL: BUILD 890PROTOCOL: CAN42_NEW_V2

The car began to "chirp"—not a programmed sound, but the rhythmic clicking of actuators and relays firing in a sequence they hadn't used since the factory floor. The needles on the analog gauges swept to their maximums and stayed there, vibrating. "Handshake confirmed," Elias whispered.

Suddenly, the screen turned a steady, calm blue. The idle of the engine, which had been a rough growl, smoothed into a surgical hum. The CAN42 bridge was holding; the car was now processing data at ten times its original capacity.

Elias slid into the driver’s seat. He didn't need a diagnostic tool to tell him the difference. He could feel it through the steering wheel—a digital heartbeat, precise and hungry.

"Build 890 is live," he said, shifting into gear. "Let’s see what she can actually do."

Should we continue the story with a high-speed test drive to see how the new protocol handles, or focus on a technical glitch that appears once they hit the open road?

The upgrade you're looking for refers to the Magneti Marelli RT3 navigation system, commonly found in older Peugeot, Citroen, and Lancia vehicles. Specifically, version 6.63 Build 890 is the final official firmware release for CAN-bus units.

Upgrading from version 6.51 to 6.63 is a standard procedure that unlocks better stability and compatibility with newer map discs. 🛑 Critical Warning: Check Your Hardware

Before proceeding, you must verify if your unit is VAN or CAN. Installing the wrong firmware will permanently "brick" (break) your head unit. Hardware Type Firmwares Start With Visual Indicator VAN-bus Version 5.xx Button under left dial says "RDS" CAN-bus Version 6.xx Button under left dial says "LIST" a 6.5-inch touchscreen

Rule: If your current version is 6.51, you have a CAN-bus unit and can safely upgrade to 6.63.

To Check Version: Hold the MENU button for 5 seconds -> Select Device Description (or System Information). ⚡ What’s New in 6.63 Build 890?

Improved MP3 playback: Faster reading and better file structure support.

Map Support: Better compatibility with final Navteq map editions (up to 2016/2017).

Stability: Fixes for system crashes and GPS signal "freezes."

Infrared Fixes: Better connectivity for systems with built-in phone cradles. 💿 How to Perform the Upgrade Preparation: Burn the .iso file to a high-quality CD-R (not RW). Use the slowest possible speed (e.g., 2x or 4x).

Engine On: Keep the engine running throughout the entire process to prevent "Economy Mode" from shutting the system down.

Insert Disc: Remove any existing navigation or music discs and insert the 6.63 update CD.

Wait: The screen may go black or restart several times. Do not touch anything until the disc is automatically ejected and the system returns to the main menu.

Confirm: Verify the new version (6.63 Build 890) in the Device Description menu. 💡 Troubleshooting

"Check CD" Error: Usually caused by a poor burn quality or a dirty laser lens. Try a fresh CD-R on a different burner.

Stuck at 0%: If the update doesn't start, ensure you aren't trying to install a VAN firmware (v5.xx) on a CAN system (v6.xx).

When to get professional help

  • If you can’t confirm file provenance/hardware compatibility.
  • If the unit fails to boot after the update.
  • If vehicle CAN systems start showing errors or unexpected behaviors.

1. Overview

The string describes a specific workflow for updating the firmware and configuration of an RT3 (often labeled RD4) head unit found in PSA Group vehicles (Peugeot and Citroën). This process typically involves flashing the system software to enable new features or correct compatibility issues, specifically relating to the vehicle's CAN Bus communication protocol.

What is RT3?

The RT3 (Radio Third generation) is a hard-drive-based navigation radio manufactured by Alpine and Continental for DaimlerChrysler. Unlike standard head units, the RT3 features a 20GB or 30GB HDD, a 6.5-inch touchscreen, voice command, and built-in navigation maps stored on the drive. The operating system runs a modified version of Windows Automotive.

Step 3: The Flash Sequence (15 Minutes)

  1. Insert the DVD-R into the slot. The RT3 will spin for 15 seconds.
  2. A prompt will appear: "Update Application? Yes / No".
    • Press Yes.
  3. The screen will go black. Do not panic. The green LED on the radio face will blink.
  4. Bar 1 (0-3 minutes): "Erasing NAND." The fan will run loud.
  5. Bar 2 (3-8 minutes): "Writing SYS.APP." This is the neural surgery. Do not touch anything.
  6. Bar 3 (8-11 minutes): "Updating CAN Gateway to CAN42 New." You will see a specific checksum: 0x8F3A.
  7. Bar 4 (11-13 minutes): "Configuring Voice DB."
  8. Final screen (14 minutes): "Update complete. Remove disc. Radio will reboot."
