This is an HDMI input adapter that can be used in vehicles with genuine CarPlay. You can display devices like a Fire TV Stick or game consoles on your car's display. Purchased on Amazon. Used for about a week. Selling because I no longer need it. Tested and confirmed to be in good working condition. 【Product Description】 - Brand: ottocast - Product Name: Car TV Mate - Connection: USB - Compatibility Requirements ・Vehicles equipped with wired Apple CarPlay ・Requires a genuine CarPlay-compatible USB port ※Cannot be used in vehicles with wireless CarPlay only or vehicles without CarPlay. The instruction manual has been discarded, so it is not included. You can understand almost everything by watching this YouTube video: ※The YouTube video explains the Car TV [Pro] and [MAX], but this product is the normal version. I think it probably only supports CAR play. https://www.youtube.com/watch?v=mj3ir9pxbAk It may not be compatible depending on the vehicle model, year, and equipment.
