Junsun Android hu and no sound

[SBN]

Installed a junsun android unit in a 2008 Audi TT, it seems like everything is connected but I have no sound... any ideas why?

From the car there is a quad connector with wires into the black quad block, there is then a green and blue connector into this from the car. The junsun unit came with a connector quad lock that went into this... not a huge amount more to do... any ideas?

Does your TT have factory Bose speakers? They often need a specific wiring adapter.
