Front and rear dash cam. Front camera 4K, rear camera 2.5K. The dash cam replaces the rearview mirror, becoming a dash cam at the same time. Mirror camera with GPS device. It has many features like lane departure warning, collision warning, blind spot detection. It has a microphone. If installed via fuse or OBD, it works 24 hours. Used for only two days. Comes with memory card. (Reason for selling: The car is being sold and I don't need it). Comes with all its accessories, all still new. I had installed it using the wires from my old dash cam and haven't removed its wires and accessories.
