I accidently browse to this site http://www.gpsdvdaudio.com/nissan-navigation_c78 . It is so cheap and looks good and beautiful .There are also many types. It is a China site . Do you know the products there? Could you give some advices ?

 

Oh , You should not doubt China w.cn . Products made in China are cheap enough and they also have good quality . People are very nice in China ,if you want to buy something ,you can talk to them ,I think they will give you a satisfied answer .
Good luck !
