Visteon R013 Radio Unlock: CAN Filter installation

Unlocking Visteon R013 1DIN radio: CAN Filter Installation Guide

The Visteon R013 radio becomes locked when removed from its original vehicle, preventing reuse in another car or testing on a bench. This security feature blocks retrofits and standalone operation.

On startup, the radio checks for a vehicle ID message on the CAN bus. While waiting for this expected unlocking message, the screen displays:
“Authentication in progress…”

If the expected message is not received — or if ID doesn’t match what’s stored internally — the radio enters a locked state and displays a warning message:
“Radio Locked. Please Contact Dealer”.

To bypass this restriction, a CAN filter for Visteon R013 (also referred to as a security code emulator or immobilizer bypass) can be installed. This device automatically learns the radio’s security ID  and simulates the required unlock message on the CAN line, allowing the radio to boot normally.

Visteon R013 CAN Filter Installation Options

To unlock the Visteon R013 radio, the CAN filter (immobilizer emulator) can be installed in two ways, depending on your use case:

1.  External Installation

Best for bench testing or quick retrofits. The filter is connected externally to the wiring harness, without opening the radio unit.
✅ Easy to install, fully reversible, and ideal for diagnostics or testing.

2.  Internal Installation

More advanced option. The filter is mounted inside the radio, directly to the PCB.
✅ Offers a clean, OEM-style integration with no visible modifications.
⚠️ Requires soldering skills and technical knowledge.

CAN Bus Filter Configuration

⚠️Important: The CAN filter must be configured for Visteon R013 units by soldering jumper J3 on the PCB.

External CAN Bus Filter installation

External installation is the easiest method and requires only a few basic connections:

🔋 Power Supply:

• +12V → Connect to ignition voltage (ACC)
• GND → Connect to ground

🔗 CAN Bus Connection:

• CAN2 → Connect to the unit’s CAN lines
• CAN1 → Optional: connect during in-vehicle installation

🔧 Note: The CAN1 connection can remain disconnected, even in a vehicle. However, it’s recommended to connect it to enable passthrough of the vehicle’s CAN traffic.

By wiring CAN1 to the vehicle’s CAN bus, the filter acts as a CAN gateway, allowing diagnostic tools (OBD) and steering wheel controls (if equipped) to continue functioning properly. This setup ensures full communication with the radio while bypassing the immobilizer lock.

Internal CAN Bus Filter installation

Step-by-Step Overview

1. Disassemble the Radio Unit

Carefully open the Visteon R013 enclosure to access the internal PCB. Remove the necessary screws and gently separate the housing without damaging the ribbon cables.

2. Mount the CAN Filter Board

Position the CAN filter module securely inside the housing. Use non-conductive adhesive (e.g., hot glue or double-sided tape) to prevent the board from shifting or contacting nearby components.

3. Identify Connection Points on the PCB

Refer to the provided diagrams below to locate power and CAN lines on the radio’s mainboard. These are where the CAN filter will connect.

4. Modify the CAN Bus Line

You must remove the existing CAN choke on a CAN line to properly insert the CAN filter in-line.

5. Solder Filter Wires to PCB

Connect the CAN filter’s wires to the appropriate pads:

• +12V ignition (pin 7 on power connector)

• GND

• CAN2 High / CAN2 Low

• CAN1 High / CAN1 Low 

🔧 Note: The CAN1 connection can remain disconnected. However, it’s recommended to connect it to enable passthrough of the vehicle’s CAN traffic.

6. Final Assembly and Power Test

After verifying all connections, reassemble the unit and apply power. The radio should now bypass the factory immobilizer lock and boot normally.
