Passat B6

[vasant3]

I have a VW passat B6 2009 model with RCD 510 touch screen cd changer radio,It does not have bluetooth function.It has front and rear parking sensors which shows on the Hu display.I am thinking of replacing the same with aftermarket dvd/gps/bluetooth model with rearview camera.The VW factory replecement model Rcn 510 is very expencive.Can someone explain how to remove exsiting player?

thanks
