If the above steps don’t match your screen, your specific Strada model may have a different firmware version. Look for icons that resemble a globe or a speech bubble with “A/B” characters, often used for language settings.

The app will overlay English text directly onto your screen in real-time, allowing you to navigate the Japanese menus with ease. 2. Firmware Updates

Disclaimer: Modifying car navigation firmware may void warranties and violate local traffic laws requiring driver focus. Proceed at your own risk.

"Okay," I read aloud from a forum post. "Turn off the unit. Hold down the specific combination of buttons."

Navigate to 機器設定 (Device/System Settings). Look for the word 言語 (Language) or an icon of a globe .
