I would greatly appreciate it if you could leave a comment before purchasing. Thank you for viewing. Please refrain from purchasing if you are sensitive to used items, as they have been stored by a non-professional. I have a cat, so I clean as thoroughly as possible, but if you are concerned, please refrain from purchasing. This is a built-in switch type TV canceler, which originally cost about 4000 yen. It's an easy-to-install type that even those unfamiliar with it can complete in about an hour. Please refer to video sites for installation instructions. I installed it in my Alphard 40 series, but I am selling it because I bought a different product. I confirmed its operation when I installed it, but as shown in the image, some navigation functions and cruise control will not work while in use. Due to the nature of the product, I cannot accept claims such as incompatibility, inability to install, or failure to operate properly. Please understand this beforehand. The following is a product description: [Allows navigation operation and TV viewing while driving] The original display audio does not allow TV/DVD viewing while driving, which is a concern for drivers and passengers. The atmosphere inside the car is also poor and uncomfortable. After installing this kit, you can watch TV and DVDs during long drives and traffic jams, making the car interior fun and comfortable without boring the passengers. It's a welcome item for families. [Easy installation] Completely plug-and-play design, no wiring modifications are required. Simply insert it between the original connectors without damaging the car's wiring. Note: Please use the switch to switch between TV viewing and navigation operation. [With switch] Solves the driver's problem by allowing TV viewing and navigation operation by switching ON/OFF! ※: In TV viewing mode (switch ON, protruding), you cannot get the current location and route guidance, so please be aware. If you need route guidance, switch to the original mode with the switch.
