video or audio in ntg1 w211

[del666]

What parts would I need to add either video in or audio in on the comand ntg 1 unit?

I bought the latest Bluetooth module thinking I could Bluetooth the music across, but I can't :fail

As far as I have searched ( again, lol) , as long it has a spare port at the back off the unit, I just need a cable.
Is that correct?

The vehicle is a 2005 e220 cdi estate with sat nav unit in the boot and viseeo mb4 in the arm rest.

Thanks in advance

Derek

Don't you have a 3.5mm aux in socket in the glovebox?
