What is the purpose of the RST hole on a car navigation system?

The RST on a car navigation system is a reset button that can restore the navigation to its factory settings. Here are the details about the RST on a car navigation system: 1. Purpose: The RST on a car navigation system is a reset button. When the navigation system freezes or the program malfunctions, you can use this button to reset it, allowing the navigation to resume normal operation. 2. Location and usage: The RST button is mostly located on the front panel of the navigation device, appearing as a small hole. When the device is powered on, use a toothpick to press into the hole. After hearing a response, restart the navigation to restore it to factory settings.
Having driven for over a decade, I've encountered navigation system freezes quite often. That small round hole marked RST is the reset button, usually cleverly hidden—perhaps along the screen bezel or near the card slot. It's wise to always keep a SIM ejector tool or similar handy for poking it. Last time when my navigation got stuck on the positioning screen, I used a paperclip to press it for three seconds, and the device immediately went black and rebooted. Note this differs from the factory reset option in the menu—it's like performing CPR on your navigation: clearing the memory without powering off, preserving map data but erasing saved addresses like home and work. When you get a new car, remember to locate the RST hole in the manual first—it's much safer than yanking fuses directly.
The girls in our car club often complain about the navigation system freezing. The RST hole is like a physical button for a forced reboot when the phone crashes, usually located on the side of the navigation screen, and needs to be pressed with a pointed object. The earring back in my bag has come in handy—when the navigation suddenly goes blank, poke this hole for ten seconds, and the screen will flash a few times before returning to normal. Note that this will clear your Bluetooth pairing records and recent navigation history, but it won't delete the built-in maps. For regular maintenance, avoid stuffing anything into the hole, and don't rinse the navigation panel directly with water when washing the car.
