Battery Drain After Installing an Aftermarket Central Control Screen?

[LolaFitz]

There are several reasons for battery drain after installing an aftermarket central control screen: Power cable connected to constant power: If the central control's power cable is connected to constant power, the navigation system will continue to consume electricity even when the car is parked, leading to battery drain and potential failure. Poor circuit contact or short-circuit leakage: Carefully inspect the circuit for any poor contact or short-circuit leakage issues. It's best to disconnect electrical devices. Issues with the large screen navigation power connection: Avoid replacing original car components unnecessarily. If there's a problem with the power connection of the large screen navigation, it may continue to supply power for half an hour or several hours after the car is turned off. Even the best battery won't last in this situation, as the large screen itself consumes a lot of power. Therefore, try to avoid modifying power-consuming components.
