  • No steering

    I have no steering wheel input. the servo screen shows no dial movement. Travel adjust & DR/EXP screen shows the that wheel is sending inputs.
    Any idea why the steering wheel isnt working? Ive reloaded an older version of software, then reloaded the current.
    Ive done a stick calibration also.

  • Display brightness

    If you want to set the display brightness for outdoor, please use the following settings:
    Display brightness: 20
    The cut-off time should be set to OFF, so it will stay at the bright display.
