Help removing CD stacker affecting tone

[Belle]

Hi All,
I tried to remove my CD stacker from the boot today as it does not load or play CD's and I dont need it anyway.
My preference is to just remove it. After disconnecting the only plug and removing, there is now no tone/sound available at all through any speakers for radio, phone etc. The display just says no tone available.
I then installed again and the tone/sound works OK.
Does anyone know if I can bypass this or does it need coding out?
As mentioned Id prefer to remove it from the vehicle.
Cheers
