Rt3 Upgrade 651 Na 663 Build 890 Can42 New Link

You might wonder: Why stop at 663 Build 890? There is a mythical Build 895 (CAN43 New) that exists only on 2010 Jeep Commander prototypes. Do not chase it. It has a bug that disables the driver's side speakers after 2 hours of driving.

Build 890 CAN42 New is the pinnacle. After this, Chrysler moved to the RB5 (MyGig 2.0) and abandoned RT3 support entirely. By performing this upgrade, you have effectively installed the "Windows XP SP3" equivalent for your car radio—the final, most stable version ever made.

If your vehicle’s infotainment shows RT3 firmware version strings like “651 NA” and you’re targeting an upgrade to “663 build 890 CAN42,” this guide explains what that upgrade is, why people do it, how to prepare, step-by-step installation of files typically involved, common pitfalls, and post-upgrade checks. I assume you have a Ford/PSA RT3 system and aftermarket nav map or firmware images that reference the versions above.

The log rt3 upgrade 651 na 663 build 890 can42 new summarizes a successful or pending operation to modernize a Peugeot/Citroën RT3 radio unit. It details the migration from legacy firmware (v6.51) to a more modern build (v6.63 Build 890) while ensuring the critical CAN Bus architecture (ID 42) is correctly defined to prevent communication errors with the vehicle's BSI.

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.

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?

This guide outlines the process for upgrading your Magneti Marelli RT3 Navigation System from version 6.51 to 6.63 Build 890 CAN.42 . This specific firmware is intended for vehicles with architecture. 1. Pre-Upgrade Verification

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

: The screen will detect the new software and ask if you wish to proceed. Press Wait (10–30 Minutes)

: The system will reboot multiple times and the progress bar may reach 100% several times. : The disc may eject and re-insert itself automatically. Do not touch it until the final "Installation Successful" message appears. : Once the system displays "Installation successful," press . The unit will reboot one final time into version 6.63. 4.
