Why is the 2017 ford explorer navigation not working?

The 2017 Ford Explore might develop issues with its navigation system for many reasons, including a software freeze. Or a disconnection in the primary controlling cable. You can try bringing it back to working condition by doing a reset of the system through the sync system. If a factory reset through the sync does not resolve the issue, You can attempt going into the navigation settings and see if there is a crucial update available. Updating the navigation to the lateSTSoftware version might bring it back to functional status. There is also a possibility that the fuse or cable controlling the nav system has blown out or come loose, and will need technical work done to fix these components.
