What Causes an In-Car Navigation System to Reboot in an Endless Loop?

[OAdam]

If your in-car navigation system keeps rebooting repeatedly, there are likely two main reasons: 1. Memory overload: When the system memory becomes too congested, it can cause the screen to continuously restart. In this case, you'll need a paperclip or toothpick (or any similarly rigid object) to press the RST hole (reset button) on the center console screen, which will restore the system to its initial state. 2. Insufficient battery voltage or a faulty relay in the fuse box: This can also lead to the navigation screen repeatedly rebooting, and replacement may be necessary. A professional automotive diagnostic tool is required to troubleshoot the issue, and it's best to have it inspected by a 4S dealership or auto repair shop.
