can anyone help with the cables photoed below ?

one cable is black connector to black connector audio + video in with audio + video out (guessing this is for reverse camera?)

the other cable is blue to blue a red,white and brown wire run outside the plastic sleeve go into a little circuit board then back in to the blue connect there is no external connections on the blue lead just the added circuit which I can't see 100%

video in motion cable perhaps

I did think that, however I did try with the analouge tv tuner turned on when I drove off, warning message poped up

ok so the blue to blue is video in motion that needs to be activated
