Thank you very much for viewing my item. This is a Carrozzeria GPS antenna. It is a GPS antenna that came with a navigation system I used previously. Since it is a used item, I am selling it as a junk item. It has been stored for a long time. Please check the photos carefully. If you cannot judge from the photos, please refrain from purchasing. No returns, no refunds, no exchanges (3N) please. Pioneer Carrozzeria
