What's new in this update

  • Improved Bluetooth stability and pairing reliability.
  • Improved wireless CarPlay and Android Auto handling.
  • Better touch response.
  • Fixes for Play Store sign-in and update issues.
  • Helps recover units with a black screen or boot loop after a previous update.

Before you start

  • Use a blank USB drive formatted as FAT32. The size doesn't matter, the format does. New drives usually ship formatted exFAT, and your unit can't read that.
  • Only update.zip goes on the USB. Don't put any other files on it.
  • Where you can, use the CarPlay USB port on the unit.
  • Keep battery voltage stable. Running the engine is ideal.
  • Don't switch the ignition off during the update.
  • A factory reset deletes your apps, settings and Google account sign-in. Back up anything important first.

Update your head unit

  1. Download update.zip and format your USB

    Download update.zip from the button above. Format a blank USB drive as FAT32. The size doesn't matter. On Windows, right-click the drive and choose Format. On macOS, open Disk Utility, select the drive and erase it as MS-DOS (FAT).

  2. Copy update.zip onto the USB

    Copy update.zip to the root of the USB drive. Don't put any other files on the USB. The update won't start if there are extra files.

  3. Boot the head unit, then insert the USB

    Turn the ignition on and let the head unit boot fully to the home screen. Plug the USB drive into the CarPlay USB port on the unit.

  4. Confirm the update prompt

    An update prompt appears on the screen. Select the update and let the unit start installing.

  5. Wait for the update to finish

    Don't turn the vehicle off, pull the USB or interrupt the unit. It'll reboot itself once the update is complete.

  6. Decline the second prompt and remove the USB

    When the unit returns to the home screen, the update prompt may appear a second time. Select No and remove the USB drive. The update is complete.

If you run into trouble

If your unit has a black screen or boot loop

If the head unit is stuck on a black screen, boot logo or reboot loop, you'll need to use Android Recovery to factory reset it before installing the update.

  1. Make sure the USB has only update.zip on it.
  2. With the head unit off, plug the USB into the CarPlay USB port.
  3. Keep the ignition switched off.
  4. Press and hold the Home button on the head unit.
  5. While holding Home, turn the ignition on.
  6. Keep holding Home until the Android Recovery menu appears.
  7. Tap the Home button to step through the menu until Wipe data / factory reset is highlighted.
  8. Press and hold Home to select it, then confirm the factory reset.
  9. Once the wipe completes, navigate to Apply Update from SD Card or USB.
  10. Press and hold Home to select. The unit installs the update and reboots itself.
  11. When the home screen returns and a second update prompt appears, select No and remove the USB.

Important: for black screen or boot loop recovery, insert the USB before you turn the ignition on. A factory reset deletes all apps, account sign-ins and saved settings.

If you don't see the update prompt

Make sure the USB is formatted as FAT32 and has only update.zip at the root, no folders, no other files. Try the CarPlay USB port specifically. If the prompt still doesn't appear, check the format again. It must be FAT32, not exFAT, and the size of the drive isn't the issue.

After recovery: reinstall once more

Once your unit has recovered and boots normally, run the update one more time through the normal on-screen prompt. This gives you the cleanest install. Insert the same USB, accept the update when prompted, then decline the second prompt and remove the USB.

If Bluetooth or CarPlay misbehaves after updating

Forget the device on your phone, then re-pair it. If the issue carries on, factory reset the head unit (Settings > System > Reset).
