Thank you for viewing. This is a TCL BMW genuine drive recorder. It's a set of front and rear cameras, GPS, harness, and box. Please prepare an SD card yourself. I am selling it because I switched to a mirror-type drive recorder about 3 months ago. It was working until I removed it, and I have stored it in the box indoors since then, so it should work without any problems. The main unit itself is relatively clean as I hardly touched it after installation. The GPS is unopened as I didn't use it. I will answer any questions you may have. Thank you.
