hello guys . now i am in Guangdong China for Canton Fair .that makes me find something ,,,hm funny or special...I am engaged in furniture industry. I don`t knew much about Electronic products, someone in China introduced me some Electronic products such as car backup camera, car DVD player and something about car parts. but the Most attract me is the GPS navigators. It is cheap out of my expectation. It is just 300$. but i don`t knew how is the quality. he gave me his website in case i want to knew more about the products. The site is car dvd gps navigation systems,car audio system. i wonder it is true or scam .
