Will Mekede MN-X ZQ9109 Integration Cause Persistent PDC Display Problems in Your BMW?

Owners of BMW vehicles retrofitted with the Mekede MN-X ZQ9109 head unit frequently report problems with the integration of the Parking Assistant and forward Park Distance Control (PDC) systems. The most common complaint is the absence of visual feedback from the front sensors and Parking Assistant when the vehicle is not in reverse, even though the audio alerts remain functional. This disrupts the seamless operation found in the original BMW setup, where the PDC display remains active until the car exceeds a certain speed.

Typical Issues Reported

  • The PDC and Parking Assistant work and display correctly when reversing, but the screen does not show sensor data when moving forward or in first gear.
  • Activating the PDC button triggers the system’s sounds but fails to bring up the visual interface.
  • Users must manually switch to the OEM menu to view sensor data, which is impractical during tight maneuvers.
  • The system immediately exits the PDC screen after leaving reverse, providing no visual aid for front parking sensors.

Root Causes

The Mekede MN-X ZQ9109 may not fully support OEM BMW protocols for forward PDC and Parking Assistant display outside of reverse gear. The head unit’s firmware or configuration may lack proper triggers to keep the PDC screen active when the vehicle is moving forward at low speeds.

Practical Solutions

Solution 1: Adjust BacCar Configuration

  1. Navigate to BacCar Configuration > Rear Car Type.
  2. Enable both “Rear Car Trajectory” and “Car Rear Radar.”
  3. Test if this restores the expected PDC display behavior.

Solution 2: Modify Personalization Settings

  1. Go to Personalization.
  2. Enable the “Radar Activation Switch.”
  3. Check if the PDC visuals now remain active as intended.

Additional Tips

  • Some users seek third-party apps to display PDC data, but native integration delivers the best experience.
  • Firmware updates or consultation with Mekede customer support may offer further improvements or compatibility patches.
  • If the issue persists, consider reaching out to BMW retrofit or coding specialists familiar with aftermarket Android head units.
