01. Outdated software

One of the common reasons for Tesla’s navigation problem is outdated software. Tesla keeps releasing the update to improve its navigation system, add new features to it, or remove bugs.

Solution:

You need to update your Tesla software to make it work properly and use its latest features.

Updating your Tesla software is a very easy process. Follow these steps to update your Tesla software,

  • Ensure that your Tesla vehicle is connected to a stable network.
  • Tap on the “Controls” icon on the screen.
  • Select “Software” from the menu.
  • Look for the “Software Update” button to check for available updates.
  • Click on “Install Now“.

02. GPS signal weakness

Weak GPS signals can also cause the navigation system to be problematic. The accuracy of your Tesla navigation system relies on strong GPS signals.

If your Tesla is not receiving strong signals due to obstruction and poor satellite coverage, your Tesla’s navigation system will not work properly.

Solution:

Restarting your car and relocating your Tesla to such areas where the GPS signals are good is the best solution you can try. Wait for at least 1 minute before turning your Tesla on.

03. Poor internet connection

A good interest connection is very necessary for your Tesla navigation system to work properly. A good internet connection is required to get traffic updates and map information.

If your Tesla has a poor internet connection, it can cause the navigation system not to work properly. Too many devices connected to the same Wi-Fi or internet connection with which your Tesla is connected can also be a reason for poor internet connection.

Solution:

Ensure that your Tesla is connected to a stable internet connection. You can also use your data to provide good interest to your Tesla.

If there are too many devices connected, disconnect them for some time or connect your Tesla with another Wi-Fi network or internet connection.

If the internet is not connected properly reconnecting with the same Wi-Fi network can also fix this problem.

04. GPS antenna malfunction

A damaged antenna can be a reason for this problem. The antenna is the device that receives the GPS signals and provides them to your Tesla to use its navigation system.

Solution:

If you suspect that there is an issue with the GPS antenna, you need to fix it or replace it with a new one. If your Tesla is under warranty, connect to the Tesla customer support service. They will fix or replace the anterior for free.

If you have some knowledge about cars and hardware you can replace the antenna by following these steps.

  • Ensure that the vehicle is parked in a safe and well-ventilated area.
  • Turn off your Tesla.
  • Open the hood of the Tesla vehicle locate the 12-volt battery and disconnect the negative terminal to disable the power supply.
  • Remove interior panels to access the GPS antenna.
  • Use the vehicle’s service manual for guidance on the specific panels that need to be removed and the appropriate steps to do so.
  • Now locate the GPS antenna. It is typically located near the roof or in the vicinity of the rearview mirror.
  • Carefully disconnect the wires from the GPS antenna.
  • Take note of their positions and connections to ensure proper reconnection later.
  • Unscrew the GPS antenna carefully and remove the old GPS antenna.
  • Place the new GPS antenna in the same spot as the old one.
  • Reconnect the wires or cables that were disconnected from the old GPS antenna.
  • Reassemble the interior panels that were removed.
  • Reconnect the negative terminal of the 12-volt battery.
  • Start the vehicle and check if the GPS antenna is functioning properly.

05. Damaged NAV SD card

In your Tesla, there is an SD card specifically for the navigation system. It is known as the NAV SD card. It stores map data and software required for the navigation system of your Tesla.

Solution:

Malfunctioning or damaging this card can also be a cause. You can easily replace your NAV SD card by using the tools in your garage.

Follow these steps to replace the damaged NAV SD card with a new one,

  • Ensure that the vehicle is parked in a safe and well-ventilated area.
  • Turn off the vehicle
  • Remove the dashboard panel from the passenger side safely.
  • Now you will be able to the right side of the MCU.
  • There will be a card slot on the upper right side of the MCU.
  • The card will be protected by some kind of rubber shield.
  • Use any sharp thing to cut this and press the card to take it now.
  • Now place the new card on it.
  • Now place the panel back in its position and everything will be good to go.

06. Lose or damaged fuse

A blown fuse can also cause the navigation system not to work. A fuse can get faulty even due to a slight change in electric power.

Solution:

Check the fuses and make sure all the fuses are okay, especially the MCU fuse. If you find any loose fuse, reconnect it again tightly. If you suspect that the fuse is blown, replace it with a new one.

07. Glitches and bugs

Glitches and bugs can also cause Tesla navigation malfunctions. Your Tesla MCU can receive bugs and glitches due to the connection of third-party apps and devices.

Solution:

01. First of all, you should remove third-party apps or devices from the MCU. This will remove the bugs and glitches of the MCU.

02. Cleaning the cache storage is also a solution to remove bugs and glitches. When a glitch enters the MCU, it is stored in cache storage. When we use an app or any system of Tesla, it also runs with it. To clear the cache storage you need to power off the Tesla.

Follow these steps to power off the vehicle,

  • Go to your touchscreen.
  • Set the Tesla in Park mode.
  • Click on Controls
  • Now on Safety & Security.
  • Now on Power Off.
  • You’ll find 2 options: Cancel and Power Off. Click on the Power Off
  • Wait for around 2 minutes. During this period, do not touch any part or open the door.

03. You can also go for a soft reset to fix this problem. A soft reset will remove the bugs and your Tesla navigation system will start working properly.

Follow these steps to perform a soft reset;

  • Ensure that you are seated in the driver’s seat and the vehicle is parked.
  • Press and hold the two scroll wheels buttons.
  • Hold the buttons until the touchscreen turns off and the Tesla logo appears.
  • Now release the buttons and wait for the touch screen to reboot.

04. If the soft reset did not work, you should go for a hard reset. Remember that all the data and information will be erased after performing the hard reset.

Follow these steps to perform a hard reset;

  • Ensure that your Tesla is parked, and the vehicle is turned off.
  • Open the front trunk and locate the 12V battery.
  • Disconnect the Negative Terminal from the battery.
  • Leave the negative terminal disconnected for at least 5 to 10 minutes.
  • Reconnect the Negative Terminal and Turn on your Tesla.
