This item was stored after being used in the past. Please assess the scratches, stains, and discoloration from the photos. The recording cable is missing. It was used in a 12V car, so it's unknown if it can be used in a 24V car (it wasn't mentioned in the manual). I tested its operation with a 12V power supply on a desk, and it worked normally. (I couldn't confirm recording because the cable is missing) I will include one ROM with a different melody (the one with the white label in the photo) and two electrical tap connectors. I have performed a basic cleaning and operation check, but it is quite old, so please understand this before purchasing.
