my g/f has a 2002 cavalier and i was wondering what all needed to be dont to put the D3 in it. I have a old deh6800 in it right now. i also have the BLACK met box in it. i am going to do the instalation myself and bypass it. i was told i can do the vss on the box and the brake/reverse light as well. Im new to the whole Nav unit instalation. what wires will be modified and what do i need to cut on the dash for it to fit. i have the bluetooth box and everythign for it.
