What to Do When the Car Navigation System Won't Turn On?
1 Answers
Solutions for a car navigation system that won't turn on: 1. If the navigation system is powered but the backlight and button lights are off, this is likely due to a burnt diode on the front screen motherboard, causing excessive current and a short circuit. In this case, seek after-sales service. 2. If the navigation system is not powered and won't turn on, remove the navigation unit and check the plastic plug on the power cable for any broken resistor wires. If broken, replace them; if not, take it to after-sales service for repair. A car navigation system features GPS global satellite positioning functionality, allowing drivers to input their destination, after which the system automatically calculates the most suitable route based on electronic maps and guides the driver along the calculated path during travel.
