What should I do if my 2015 Subaru Legacy touch screen is unresponsive?
If your touch screen is unresponsive, start by performing a soft reset. This can typically be done by holding down the “Power” button on the infotainment system for about 10 seconds, or until the screen turns off and then back on. This action can often resolve minor glitches without losing any of your settings or data. Make sure your vehicle is in the “On” or “Run” position during this process.
If the soft reset doesn’t work, check the fuses related to the touch screen functionality. Locate the fuse box—usually found under the dashboard or in the engine compartment—and refer to the owner’s manual to identify the correct fuse. If the fuse is blown, replacing it may restore the touch screen’s functionality. If the issue persists, consider consulting a professional technician.
How do I reset the Subaru Legacy touch screen to factory settings?
To reset your 2015 Subaru Legacy touch screen to factory settings, navigate to the “Settings” menu on the screen. Look for an option that says “Reset,” “Restore Factory Settings,” or a similar phrase. Select this option and confirm your choice when prompted. This will erase all personal settings, including Bluetooth connections and saved preferences, restoring the system to its original state.
After the reset is complete, you may need to re-pair your phone and adjust your preferences again. Make sure to back up any important contacts or information associated with the previous settings, as this process cannot be undone. Factory resets are useful for resolving persistent issues that minor troubleshooting steps cannot fix.
Why does my touch screen keep freezing?
A freezing touch screen in a 2015 Subaru Legacy can be caused by a few factors. One common reason is software bugs or glitches, which can occur from time to time in any infotainment system.

If freezing happens frequently, consider checking for any available software updates.
If software is updated but the problem continues, it may indicate a hardware issue, such as a failing touchscreen or wiring problems. In such cases, visiting a Subaru dealership or a qualified technician would be advisable to diagnose and rectify the underlying cause effectively. Regular maintenance and updates can help mitigate instances of freezing.
Can I upgrade the software on my touch screen?
Yes, you can upgrade the software on your 2015 Subaru Legacy’s touch screen. Subaru periodically releases software updates to improve system functionality, address bugs, and enhance user experience. To check for available updates, visit the official Subaru website or your local dealership for guidance on the specific process for your vehicle’s model.
Before proceeding with the update, ensure you have proper instructions to avoid complications during the installation. Typically, updates can be done via USB drives or with the assistance of a dealership. Making sure your vehicle is parked and the ignition is on for the entire update process is crucial to avoid any interruption that could cause further issues.
What do I do if my touch screen says “No Signal”?
If your touch screen displays a “No Signal” message, begin by checking your device connections, particularly if you are attempting to use features involving external devices like a smartphone or USB. Ensure that your cable is functional and securely connected. Sometimes, simply unplugging the device and re-plugging it can resolve the issue.
If the problem persists, try restarting both the touch screen and the external device. If you are using Bluetooth, make sure the pairing is correctly set up and that your phone or other devices are within range. If you continue experiencing “No Signal” after troubleshooting these steps, there may be deeper connectivity issues that warrant a visit to your Subaru technician.
What are possible causes of the touch screen displaying an error message?
Error messages on your touch screen can stem from various causes, including software glitches, incompatible devices, or issues with installed apps. When this happens, it is advisable to restart the system first to see if the error clears. Soft resetting the infotainment system often resolves minor software conundrums without loss of data.
If restarting the system does not fix the problem, consider whether any recent changes might relate to the issue, such as new device connections or app installations. If the error persists after troubleshooting, contacting a Subaru dealership for assistance or checking for software updates is recommended to resolve underlying software or compatibility issues.
How can I improve the responsiveness of my touch screen?
