Should You Update Your TEYES Head Unit Firmware?

by TEYES Australia

Update your TEYES head unit when a release for your exact hardware addresses a problem you have, adds a feature you need, or TEYES support recommends it. Start by checking the release notes and your current version. If the issue began after wiring work or affects just one app, diagnose that first so you can choose the right fix.

Identify what actually needs updating

  • Head unit firmware updates the system software. Match the download or on-device update to the exact model and hardware variant.
  • An app update may be enough if only a single app is affected. Record the app version and check whether other apps have the same problem.
  • CANbus decoder firmware or configuration is separate. If wheel buttons, climate displays or the factory amplifier are affected, check the harness and vehicle profile with TEYES before changing decoder software.

Find your model and software version

Write down the exact model, current build and any variant listed in the device information. CC4, CC4L and CC4 Pro are separate models. Older models can also have separate standard and 360° firmware. When the label or software information is ambiguous, send both to TEYES support for confirmation.

Before starting an update

  1. Photograph the vehicle and CANbus settings, camera configuration, and any audio tuning you want to restore. Back up personal files and note which apps or offline maps you may need to set up again.
  2. Use the official instructions for your model. Follow the method shown there, whether that is the unit’s OTA app or a specific package.
  3. Allow time for the update with a stable power supply. Keep the vehicle safely parked and leave power connected until the process finishes. If it fails, record the error and ask TEYES before trying a different file.
  4. After the unit restarts, confirm the build and test audio, wheel buttons, phone projection and camera functions before driving.
