🔍 W220 Serial Number Location Methods

Method 1: COMAND 2.0 System Menu

Standard Access:

  1. Turn on COMAND system
  2. Press Setup button
  3. Navigate to SystemVersion
  4. Look for "Hardware" or "Serial Number"
  5. Write down complete number (format: NTG2xxxxx or AL29xxxxx)

Alternative Navigation:

  1. Main Menu → Settings → System Information
  2. Scroll through information screens
  3. Look for device identification

Method 2: Engineering Mode (Advanced)

⚠️ CAUTION: Advanced Users Only

  1. Turn COMAND system off completely
  2. Hold down these buttons simultaneously:
    • Back + Phone + Hang-up
  3. While holding buttons, turn system on
  4. Engineering menu should appear
  5. Navigate to hardware information
  6. IMPORTANT: Exit properly to avoid system issues

🚨 Engineering Mode Warning

Engineering mode allows access to advanced system settings. Incorrect changes can damage your COMAND system. Only use this method if standard menu access fails.

Method 3: Physical Unit Access

COMAND Unit Removal:

  1. Remove dashboard trim carefully (multiple clips)
  2. Disconnect COMAND unit connectors
  3. Extract unit from dashboard
  4. Look for white/silver label on unit
  5. Serial typically on back or side panel

Professional Recommendation:

W220 COMAND removal requires significant dashboard disassembly.We recommend trying software methods first. If physical access is needed, consider professional assistance to avoid damage to luxury interior components.

🖥️ COMAND 2.0 Special Procedures

🔧 COMAND System Reset

Sometimes needed before code entry:

  1. Turn off vehicle completely
  2. Wait 30 seconds
  3. Start vehicle and let COMAND fully boot
  4. Check if lock screen appears
  5. If no lock screen, proceed with reset procedure

🔄 MOST Bus Consideration

W220 uses fiber optic network:

  • Audio amplifier must be connected for full functionality
  • Broken fiber optic cables can affect radio operation
  • Multiple control units communicate via MOST
  • System errors may require professional diagnosis

🎵 Audio Amplifier Integration

Bose systems have additional considerations:

  • Amplifier may need separate reset after unlock
  • Speaker calibration might be required
  • DSP settings may revert to default
  • Professional calibration recommended for optimal sound

⌨️ W220 Code Entry Instructions

COMAND 2.0 Code Entry

  2. If locked, system displays "Enter Code" or "CODE"

    • Press center button to confirm
    • Move to next position
  6. After entering all 4 digits, select "OK"
  7. System should unlock and resume normal operation

If Standard Method Fails:

  3. Early 1999-2000 models may have different menu structure

Audio 30 APS Code Entry

❓ W220 S-Class Owner FAQ

Q: My S500 COMAND shows black screen but power LED is on. Will unlock code help?

A: Black screen with power LED usually indicates hardware failure, not anti-theft lock. Try pressing power button and check if screen responds. If completely unresponsive, COMAND repair may be needed rather than unlock code.

Q: After battery replacement, my S320 radio locks frequently. Is this normal?

A: W220 models are sensitive to power interruptions. Frequent locking suggests battery/charging system issues. Check alternator output and consider using memory saver during future maintenance.

Q: My S430 Bose system has no sound after unlocking. What's wrong?

A: Bose amplifier may need separate reset. Try disconnecting battery for 10 minutes, then reconnect. If problem persists, MOST fiber optic network may have issues requiring professional diagnosis.

Q: Can I prevent my S600 radio from locking during service?

A: Use memory saver device during battery work. Inform technicians about radio lock sensitivity. Some Mercedes specialists can disable anti-theft temporarily during major electrical work.

Q: Is it safe to enter engineering mode on my S55 AMG COMAND?

A: Engineering mode should be last resort. Incorrect settings can damage COMAND system. Try standard menu access first. If engineering mode needed, document all original settings before making changes.

Q: My 2000 S-Class has different COMAND than 2005 model. Same procedure?

A: Early W220 (1999-2002) vs late (2003-2006) have COMAND variations. Basic unlock principle same, but menu navigation may differ. Our service covers all W220 years with appropriate instructions.
