Thank you very much for viewing. As the title suggests, this appears to be a GPS antenna for a car navigation system. Some of the numbers are partially faded, and since it was given to me, I don't know which car model or manufacturer it's for. I believe it's likely for Toyota or Daihatsu vehicles, but I'm not certain. Therefore, please confirm based on the photos. Also, it has been stored at home, and I have not confirmed whether it powers on. Please refrain from purchasing if you are concerned. Thank you for your understanding.
