I installed it once, but it was removed because it interfered with the small storage compartments that are common in small cars, making it unusable. I installed it in a car with two front speakers, so only the front speaker harness has been socketed. As you can see in the image, it supports Japanese display. Operation has been confirmed with Android Auto and Apple CarPlay. Steering wheel remote control and regular remote control are included. Please ask if you have any questions. No returns or exchanges accepted.
