Who are you??

hi guys can anybody tell me what the little silver module is under the sat-nav dvd drive in the n/s/r compartment of my '02' vogue. i've just been looking and for some reason it is unplugged. the sound keeps coming and going on my radio and the telephone light has stopped flashing and disappeared from the menu. Any ideas?? cheers

Phone module ? Satnav ? amp ?

i think it could be the phone module but i'm unsure, it is not on the boot floor its fastened above the dsp amp under the satnav drive.

Voice recognition ECU?
