Smart Driving Assist System 8-inch • Model Number: GTR8 • 8-inch Digital Panel with Capacitive Touch Screen • Built-in GPS Navigation • Radar Warning (Optional) • Supports Gravity Sensor • Cycle Recording • Bluetooth Music • Memory Card: 32G TF • FM Transmitter • HD Multimedia Player This is a mirror-type drive recorder, and it seems to also function as a navigation system and multimedia player. I've extracted this information from the product page, but it's unclear whether the navigation map will properly display in Japanese. The instruction manual is in English, and it seems that only English and Chinese are available as system language options. Although it's an unused item, I've opened it to check the instruction manual. Thank you.
