- Verify that the operating voltage to the decoder is within the +9V to +16V range.
- Confirm that the CAN Bus settings on your Android head unit are correctly configured (manufacturer "Raise", correct car model and year).
- Ensure your Android head unit has the required 8-pin connector for serial communication.
Unable to Access CAN Bus Settings on Head Unit:
- If a factory password is required and the common ones (3368, 1617, 8317, 8888) do not work, contact your Android radio vendor for the correct password.
Intermittent Functionality:
- Check for loose connections or damaged wires.
- Ensure the decoder is securely mounted and not subject to excessive movement.
Unsure About Fitting or Wiring:
- It is strongly recommended to contact the seller for support or consult a professional installer before proceeding with installation to prevent damage.

9. User Tips

Verify NTG Version for Newer Models: For Mercedes Benz models, especially those from 2019 onwards (e.g., GLC 250 2019), it is advisable to verify the NTG (New Telematics Generation) version of your multimedia system. Some newer models might use NTG 5.5 or later, which could have different compatibility requirements than earlier versions. Always confirm with your head unit vendor or the seller if your specific NTG version is supported.
Consult Head Unit Manual: The setup process on Android head units can vary significantly. Always refer to your specific head unit's user manual for detailed instructions on accessing and configuring CAN Bus settings.
