Extra pair of Av Leads in boot?

[hamlet]

'06 E53, Nav with TV, Cd Stacker,Non-DSP, Bluetooth, Fold up DVD screens mounted to rear of the front seats, DVD for these in the boot, opposite side to the CD Stacker, NAV cd etc.

Behind the DVD stacker there is two sets of av leads (Yellow/Red/White). They are taped up and I am wondering if anyone knows where they connect to? They are not the second AV in's on the rear DVD screens because these are separate again.


Thanks in anticipation
