This guide is intended to be used when uninstalling a NaviLink from a vehicle it's already been installed into, and replacing it with the upgraded bluetooth version of the device.



Uninstallation of existing hardware



  1. Locate your vehicle's existing NaviLink device. By default this device would have been installed behind the dash of your vehicle.

    • This device is connected to a large wiring harness.

    • A portion of this harness connects to your vehicle's ECM by way of an adapter or directly into the diagnostic port.

    • A similar portion was used as a Y-connector to provide you a diagnostic port to use while we used the vehicle's stock diagnostic port for vehicle data

    • A portion at the opposite end has a USB cable connected and feeds back out under the dashboard of your vehicle.

  2. Disconnect the wiring harness from your vehicle and your Navistream tablet. Remove any and all adapters that are attached as well.

  3. Remove all parts from the vehicle and place aside in a safe location.

  4. If your NaviLink was connected to your vehicle's diagnostic port, feed the original stock diagnostic port back through the dashboard bulkhead and secure it tightly.


Your vehicle should now be back to the original stock configuration before Navistream was installed.



Installation of Upgraded Hardware



  1. Make sure your vehicle engine is off

  2. Insert the new NaviLink into the vehicle diagnostic or telematics port of the vehicle.

  3. Secure the device to the inside of the vehicle so it does not interfering with the vehicle operator when they're in the driver's seat.

  4. Turn on the vehicle engine.

    • You should see a fast flashing green LED, indicating that vehicle bus activity has been detected.

    • After the green LED becomes solid, the device is registered on the vehicle bus. Note that for power management reasons the LEDs may not remain on.

  5. Plug the included 5v USB charger into your vehicle's cigarette lighter (or other power source) port.

  6. Connect the Navistream tablet to this charger with the provided USB cable.

  7. Verify that the tablet is charging, then power the tablet on if it's not already.

  8. On the Navistream login screen, press the HOME button 7 times rapidly to enter the Support Menu.

    • The HOME button shape and location can vary depending on age and model.

    • On older tablets it is a physical button beside the screen on the opposite end of the tablet from the USB port.

    • On newer tablets it is a software button that looks like a small circle and is located on the bottom portion of the tablet screen itself.

  9. Touch the INSTALL tile.

  10. Touch the NEW INSTALL tile.

  11. Touch the NAVILINK 3 tile. Please contact support if you do not have this button available to you.

  12. Restart the Navistream Tablet by holding the power button, touching RESTART, then touching RESTART once again.

  13. Upon restarting, Navistream will automatically connect to the bluetooth NaviLink device.


Please note that if you are receiving an ECM connection notice on the login screen after performing all the steps above, then there may be an issue.

  • Go back through the above steps and make sure all devices are connected per the instructions.

  • If you're still running into problems and all steps are done correctly then please call support for assistance.



Verification of Engine Data after Installation



  1. With the vehicle engine running, press the HOME button 7 times rapidly on the login screen.

  2. Touch the INFO tile

  3. Use your finger to scroll down this page until you see a section for ECM Connection
  4. Here you will see many data values, but an instant indicator that things are working are the vehicle speed and RPM values.

    • Speed should show as zero at rest, and resting RPM is likely somewhere between 600 and 1000 RPM.

    • If you see N/A or NULL on these values, then please contact support for help in verifying the installation is done correctly
