It's big. Right on the dashboard, it obstructed the view too much. So I mounted it a bit lower by the front vents so that only a small part sticks out, and now it's OK. The front camera is bright and of good quality. Videos are clear even in dark surroundings. It's probably not 4k since it says Full HD on the lens. I didn't connect the rear one permanently; I just checked if it works. Basic functionality. The navigation works quickly. It records, sound via BT or FM is available. The IPS screen has good angles and sufficient brightness. It doesn't have its own power supply. It turns on automatically when voltage is supplied through the USB port. Access to the ports is difficult. Overall, a successful purchase.
It works, but I haven't installed it yet. Everything is fine with it, it's a very large display, I hope I can find a place for it, Seat Altea Freetrack.
