Thank you for viewing! This is a navigation system specifically for the Prius 30 series. The screen size is 9 inches, making it very easy to see. The larger navigation screen significantly updates the interior's look! Bluetooth is enabled! Also, by tethering with your smartphone, you can use YouTube, Netflix, and more! Apps like Netflix can be downloaded from the Play Store. 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 use the original back camera, a conversion coupler is required. It's available for an additional 3,000 yen. Please comment before purchasing if you'd like it. The navigation system uses the latest version. Accessories like microphones may or may not be included, but there are no issues with installation or use. Please understand this. The product is new and in stock. It will be shipped on the same day or the next day. Please feel free to comment if you have any questions.
