Upgrading your Peugeot or Citroen RT3 system from version 6.51 to 6.63 (build 890)
is a common procedure for CAN-bus vehicles to improve system stability and feature support. This specific firmware (CAN 6.63) is the final official software version available for RT3 CAN systems. Key Benefits of Version 6.63 Build 890 Enhanced Compatibility
: Better support for newer map sets and points of interest (POIs).
: Resolves stability issues and glitches present in older 6.x versions like 6.51. Audio & UI
: Improved sound quality, better volume control, and updated user interface graphics. CAN-Bus Efficiency
: Optimized communication between the head unit and the vehicle's other electronic modules. Upgrade Procedure Verify Hardware : Ensure your RT3 system is a
version (starting with version 6.x). VAN-bus systems (starting with 5.x) are incompatible and may be damaged if this software is applied. Prepare Media Download the update files (often found as RT3_CAN_v6.63_b890.iso or similar). Burn the contents to a high-quality blank CD.
: Use the slowest possible burn speed (e.g., 2x or 4x) to ensure the RT3's older optical drive can read it reliably. Installation Keep the engine running
throughout the entire process to prevent "Economy Mode" from shutting down the system mid-update, which can "brick" the unit. Insert the CD into the RT3 head unit.
The system will automatically detect the disk and ask to proceed. The process typically takes 20–30 minutes The system will reboot several times;
eject the disk or turn off the ignition until the standard radio/navigation screen reappears. Troubleshooting & Sources Dealer Access
: While some dealers may still have access to official disks, many prefer to refer owners to online forums like the French Car Forum for legacy support. Official Tools : Modern updates are sometimes handled through the MyPeugeot App

Upgrading from a 651 NA to a 663 build 890 with Can42 has been an excellent decision. My RT3 now performs at a whole new level, and I'm loving every minute of it. If you're considering a similar upgrade, I hope this post has provided valuable insights.
Questions?
Based on the terminology used, this text refers to a software update for a vehicle’s Navigation and Telematics system. Specifically, it relates to the PSA Group (Peugeot and Citroën) vehicles equipped with the RT3 navigation system.
Here is a breakdown of what this string means and what it implies for the vehicle owner.
Real-Time Grade Compensation
Uses CAN42’s enhanced 2 kHz polling to sample pitch/grade sensors 5x faster than v651. Automatically adjusts notch output every 150ms (was 500ms) to prevent slack action.
Consist Synchronization Protocol (CSP)
Enables leader-follower alignment with <0.5% velocity deviation across 8 linked units. Replaces v651’s asynchronous broadcast method. rt3 upgrade 651 na 663 build 890 can42 new
Fail-Safe Degradation Mode
If CAN42 heartbeat is lost for >200ms, ASCC gracefully steps down to v651-compatible limp mode without emergency brake penalty.
If you are looking at this text because you found it on a CD, a download site, or a forum, you are likely in possession of a firmware update file for a Peugeot or Citroën RT3 Navigation system.
Recommendation:
This text is strictly technical nomenclature for automotive embedded software.
The "RT3 upgrade 651 NA 663 build 890 CAN42 new" refers to a specific firmware update for the Magneti Marelli RT3 infotainment system, commonly found in older Peugeot, Citroën, and Fiat vehicles.
This software version is designed to update the system from older 6.xx builds to the more stable 6.63 (Build 890), which is the final "CAN-bus" version of this hardware. Key Improvements in Build 890 (6.63)
System Stability: Fixes common software crashes and "freezing" issues during navigation or MP3 playback.
Performance: Offers faster menu scrolling and improved boot times for the main unit.
Bug Fixes: Resolves issues with Bluetooth connectivity (for units equipped) and incorrect map positioning that occurred in earlier versions like 6.51.
Expanded Compatibility: Ensures the system can properly read newer map discs and CD-R discs with high-bitrate MP3s. User Consensus
Users generally recommend this update as it is the most polished version of the software. Many report that it restores functionality to units that had become sluggish or unresponsive over time. Installation Precautions
Hardware Check: This specific build (6.63) is only for CAN-bus vehicles (typically with orange/red menu screens). Using it on older VAN-bus vehicles (version 5.xx) can permanently "brick" the unit.
Engine Running: Always perform the update with the engine running to prevent "Eco Mode" from cutting power during the 10-15 minute installation process.
Disc Quality: Use a high-quality CD-R burned at the lowest possible speed (1x or 4x) to ensure the aging RT3 laser can read the data without errors. Rt3 Upgrade 651 Na 663 Build 890 Can42 New 2024-2026
Upgrading Your RT3 System: Moving from 6.51 to 6.63 Build 890 (CAN 4.2) Upgrading your Peugeot or Citroen RT3 system from version 6
If you are driving a Peugeot, Citroën, or Fiat equipped with the Magneti Marelli RT3 multimedia system, you know that keeping the software current is key to a smooth driving experience. Moving from version 6.51 to the latest 6.63 build 890 (CAN 4.2) isn't just about changing numbers; it's about unlocking better stability and modern compatibility for your vehicle. Why Make the Jump to 6.63?
While version 6.51 was a solid foundation, the 6.63 build 890 update is considered the definitive "stable" version for CAN-bus vehicles. Here is why enthusiasts recommend the RT3 upgrade to 6.63:
Improved Device Compatibility: Experience better handshake reliability with newer mobile phones via Bluetooth and improved MP3 playback.
System Stability: Build 890 fixes several "legacy" bugs found in 6.51, reducing the frequency of system freezes or spontaneous reboots.
Faster Navigation: Users often report snappier response times when calculating routes and browsing maps.
Security Patches: Newer builds include essential fixes for system vulnerabilities, keeping your infotainment hardware safe. Pre-Upgrade Checklist Before you begin, ensure you have the following ready:
A high-quality blank CD: The RT3 is notoriously picky with media. Use a reputable brand.
Burning Software: Use a program like ImgBurn and select the lowest possible burning speed (1x or 2x) to prevent data corruption.
Stable Power: Never attempt the upgrade on battery power alone. Keep the engine running throughout the process to prevent the car from entering "Economy Mode," which will brick the unit if it shuts down during the write. The Upgrade Process
Download and Extract: Locate the RT3 CAN Software v6.51 a v6.63 build 890.rar file and extract the ISO.
Burn the Disc: Burn the extracted ISO image directly to your blank CD.
Insert and Wait: With the engine running, insert the CD into the RT3 unit. The system will detect the update and ask for confirmation.
Hands Off: The unit will reboot several times. Do not turn off the ignition or eject the disc until the main menu reappears and stays stable. RT3 Upgrade 6.51 Na 6.63 Build 890 CAN.42 - Facebook
