My Gorilla car navigation system broke, so I bought this from a seller to try it out. I no longer need it because I bought another car navigation system before this one arrived. I only tried it out briefly. For those interested and those who understand it's been stored at home, Thank you very much. m(_ _*)m Below is the seller's description: This is a GPS antenna for Gorilla mini Gorilla car navigation systems. Please check the shape in the image. Although it is not a genuine product, it uses the latest circuit board, so it is expected to have the same or better sensitivity than the genuine product.
