Beginning the Update

Note: When updating the unit, make certain that power is not interrupted while the update is in progress. If power is lost or interrupted the unit may become inoperable. Also, before starting the update, turn-off Demo Mode in the “Settings Menu” (Go to the Settings Menu > General > Demo Mode > OFF).

Note: This update must be loaded two times due to memory architecture changes and previous software versions.

  1. Ensure head unit is OFF.

  4. The update process will begin automatically upon power up.
  5. After a few moments, a TFT calibration screen will display on the TFT.
  6. Press and hold the “cross hair” with your index finger until it moves to the next calibration sector.
  7. After you press and hold top right-hand corner for calibration, the screen will ask you to “tap” the TFT again to save the settings. Tap the TFT.
  8. After the next update section, a display prompt will ask you to remove the microSD card. Remove the card.
  9. The update will continue and the unit will reboot and may display a red line.
  10. Insert the update microSD card again, push the reset button (You may have to push the volume control to turn the unit ON) and update the unit a second time.
