What are these?

[rstoughy]

What are these boxes for and can I remove them without any issues?

I'm all too aware of the CAN system on these cars that interlinks lots of things so a little concerned about removing stuff.

I'm pretty sure this is all for the ICE that originally come with the car but hopefully someone can confirm.










And this load of wires which was originally for the amps, sat nav, DVD etc??
If I trace these back and remove will I get issues??
