The Ford SYNC 3 navigation features make it convenient for everyone to travel to their destination, but what if your SYNC 3 display shows the "Navigation Fault, visit dealer for assistance" or "Navigation Fault, Navigation is not operating properly" error? Well, we researched this issue and have the answer for you.
If your Ford SYNC 3 display shows a "Navigation Fault" error, these are the primary causes and how to fix them:
- APIM has a problem and has been unable to obtain a GPS fix. We suggest you reset your module.
- The GPS antenna has failed, so you need to replace it with the new one.
- Problem related to GPS
- System updates needed
These are the primary reasons your SYNC 3 display will show the Navigation Fault errors. Please continue to read as we discuss other possible reasons and information about the Ford SYNC 3 Navigation Fault error and additional errors that you might encounter while using the Ford SYNC 3.
What Is Ford SYNC 3 Navigation?
Ford SYNC 3 navigation is a satellite navigation system that allows you to arrive at your destination quickly while watching current traffic updates. The latest SYNC 3 incorporates Waze navigation, Alexa integration to your in-car display, and accessibility to Apple CarPlay and Android Auto for Ford drivers, with general performance improvement.
The SYNC 3 AppLink function enables the system to link to particular applications on your smartphone and show them on the main touchscreen while driving. You can also control these applications through the car's steering wheel controls or the Voice Command system.
SYNC 3 also remembers all of your previous searches and places of interest, allowing the system to naturally fill your search and give recognizable locations such as that charming coffee shop, a favorite restaurant, or a friend's new house.
Why Doesn't the Ford SYNC 3 Navigation Work?
Using a Master Reset to Repair the SYNC 3 Navigation Fault
The most straightforward way to remedy this error is by applying a "Master Reset" on your Ford SYNC 3. To do this, first, disconnect any USB-connected peripherals. After that, navigate to Settings > General > Master Reset on your Sync 3 display. This restores your module's factory default settings.
Please bear in mind that this will also remove all associated Bluetooth devices, as well as devices configured for Apple CarPlay and Android Auto. If your car continues to have GPS signal problems, we recommend changing the GPS antenna.
Using a New APIM to Repair the Sync 3 Navigation Fault
Think of the APIM (Accessory Protocol Interface Module) as the main brain of your Ford vehicle. It has multiple sensors that receive input. These inputs allow communication between the module and the steering wheel controls, the radio, the navigation system, and even the user's phone via Bluetooth.
The Navigation Fault might be a symptom of a deeper problem for your SYNC 3. If master resetting and replacing your GPS antenna have not resolved your Navigation Fault issue, we strongly propose purchasing a new programmed APIM for your car.
Weak GPS Signal
Ford SYNC 3 occasionally fails to connect to GPS or switch on the car's sound system. This may prohibit you from utilizing your car's GPS, activating the music system, or connecting to the internet.
You may also attempt to clear the navigation issue from the test settings menu, but you must be stationary.
The GPS signal's intensity might be a factor in navigation mistakes. The GPS device is located at the base of the roof aerial and is prone to erosion. The navigation issue became increasingly common and was finally replaced with a no GPS fault.
You will need to replace a Fakra connector (located at the base of the aerial on the inside of the roof liner), which is a pain in the backside but should fix the problem.
One of the reasons you may be getting errors is that a system update is needed, and you haven't updated your SYNC yet. This may need a for scan programming to fix it. Test the connection with another device; contact the service provider if the access point requires a subscription.
How To Update SYNC 3 Navigation System?
- Go to the SYNC and Navigation Update page for further details.
- Enter your Vehicle Identification Number (VIN) and click the Check for Update button.
- Go to the Navigation Updates drop-down menu and follow the steps.
