9-inch portable car display allows you to view navigation on a large screen. - Model: DX-CDA901 - Size: 9 inches - Power: DC12-24V - Installation: Portable, no construction required Thank you for viewing. This is a display audio system compatible with Android Auto and Apple CarPlay wireless connection. I used it for about a week, installed in my wife's used kei car. The operation is comfortable, and you only need to connect via Bluetooth once. When you get in the car with your smartphone and start the engine, it connects automatically. Of course, it disconnects automatically when you turn off the engine. The product was comfortable to use, but it blocked a large portion of the driving view when placed on the dashboard of my wife's car, so I stopped using it. I think it can be used in cars with large windshields and long hoods. Since it has been installed once, the adhesive tape has been used. I think it can be installed in any car if you have strong double-sided tape. Please search the website for product details.
