📎 CCC M-ASK Programming | BMW E90, E60 (2005 545, 2007 335i)

• No sound with replacement CCC M-ASK. Required Programming.
  • Replacement requires programming. Used ISTA-P, reprogrammed whole CCC aggregate.
    • Coding made chime sound to work, not audio sound.
    • Re-program all CCC related parts ➱ select CCC-Aggregate.
      • If asks for BO codes to activate “Voice Control”, just skip this step.
        • It didn’t affect result in fixing sound problem.
      • Programming just CCC-M-ASK didn’t make it produce sound.
    • After programming, turn ignition off for a few minutes (not 10 seconds). After that, start the car, and the sound system should start working.
