Thank you for viewing! This is a navigation system specifically for the Prius 20 series. The screen size is 9 inches, making it very easy to see. The larger navigation screen significantly updates the interior, giving it a fresh look! Bluetooth is enabled! You can also use YouTube, Netflix, and more by tethering with your smartphone! Apps like Netflix can be downloaded from the Play Store. Of course, CarPlay and Android Auto are also supported. Each unit has been tested for power, so the box has been opened once. Regarding installation, it's designed specifically for the vehicle, making it a simple plug-and-play setup. However, if you lack installation knowledge or confidence, please have a professional install it. If you want to add a backup camera, it's an additional 3000 yen for an aftermarket camera. Please comment if you'd like one. The product is new and in stock. We will ship it on the same day or the next day. Please feel free to comment if you have any questions.
