Hello, I have update today maps on my navi unit via HDD copy method, it's a EU model B9016 from 2009. I didn't pay attention when I have removed unit if all connectors on the back side busy or not, but when I have back unit I notice that black port is free. I double check and didn't find any free wire or connector, but just wanna double check if I have missed something. Does anyone know what is black port used for ?
I have investigate by my self on other forums and that seems to be Ipod/USB/CD Changer port. So it's OK to be unused in my case.
