This is the main power board printed circuit board (PCB) for a Toyota Sequoia and Toyota Tundra.
Signs that you may need to replace this component include a black navigation screen, a blank screen, or extremely dim screen.
A failed LCD screen can also produce the same symptoms and it is important that you know for certain which component in your unit is failing. If you are not 100% positive which part is failing, we recommend you ship your navigation unit to ATR for a full diagnosis.
WARRANTY — This part has a 12 month warranty against defect and cannot be returned once installed in the event that it did not restore screen functionality.
