2012 Scirocco revers camera

[Healeypilot]

Have just bought a 2012 Sirocco R. It has an aftermarket Alpine head unit. Everything seems to work ok but anytime I touch any switch below the head unit like aircon or seat heaters the revers camera appears on the screen. Any clues on what is wrong before I pull the head unit out to investigate?
Cheers

Sounds like its software related (Alpines software) or an issue with how Alpine integrates with the cars factory electronics.
