What is the solution for navigation system restarting upon ignition?
2 Answers
The solution for navigation system restarting upon ignition is: There are several key wires behind the navigation device, one is the 12V constant power supply, and another is the Acc which is also 12V, serving as a control power supply. When igniting, the Acc has no power, so the navigation system stops working. After a few seconds when the Acc power is restored, the navigation system can restart. Car navigation systems feature GPS global satellite positioning functionality, which utilizes in-vehicle global positioning systems combined with electronic maps. Drivers only need to input the destination into the car navigation system, and the system will automatically calculate the optimal route based on the electronic map, providing turn-by-turn guidance during driving or before turns to follow the calculated route.
It's really annoying when the navigation system restarts during car ignition, and I've encountered this issue several times. The common cause is unstable power supply voltage, especially in older cars where battery output fluctuates significantly. In such cases, first check if the battery has sufficient charge; a sudden load increase during ignition with low battery can affect the navigation. Fuses are also a common failure point—open the fuse box, locate the fuse corresponding to the navigation system, and replace it if it's blown. Sometimes, software bugs can cause the problem—try restarting the navigation system by holding the power button for ten seconds to force a reboot and see if that resolves it. If updating the firmware, download the patch from the official website and upgrade via USB. Last time, I fixed poor contact by cleaning the battery terminals. Don’t overlook electrical health during regular maintenance.
