Your Subaru is equipped with over the air “OTA” software update capability. Follow these steps to
update your software and maps to improve software performance and functionality.

the update process.

3. Once the vehicle is in a safe location, be sure the vehicle is in Park if CVT or Neutral if MT and the
parking brake is fully engaged.
4. Unplug any devices, cables or other USB drives from the vehicles USB ports.

Step 1- Prepare Your STARLINK System

If the system shows your version as REL_UF.20.28.70 you are already up to date with the latest
software and map updates.

If the system shows your version as REL_UA.19.36.70 you are already update to date with the
latest software, but you don’t have the latest map update. If you would like to update your maps,

Choose Your Update Method
You have two options to update your Subaru:
1. Option 1- Via a WI-FI connection: This will update the multimedia system software but not the onboard TomTom navigation maps.
2. Option 2- USB Drive Using Your Computer: This will update the multimedia system software AND
the TomTom navigation maps at the same time.

Option 1- Wi-Fi Connection Method
Step 1- Connect your Subaru to an active Wi-Fi connection:

•

Connect your Subaru vehicle to an active Wi-Fi connection.

•

You can use one of two Wi-Fi sources. NOTE: This update uses at least 100MB of data so, choose a
WI-FI connection with no data restrictions. NOTE: Wi-Fi connections that require acceptance or login to
a web page (such as a coffee shop or hotel) cannot be used.
Choose from:
•
•

•

Your home Wi-Fi (if it reaches your driveway or parking location)
Your phone’s Wi-Fi hotspot (if your phone and data plan are capable).

To connect to whichever Wi-Fi source you prefer, follow these steps:
•

Go to Settings on your vehicle multimedia screen.
