I have a 01 X5 w/nav dsp, and trying to install a AVIC D3 HU. I am trying to keep the factory amp and 2 parts I dont know what they are nor whats there function. The frist picture has AMP on it. Can I tap into those wire for the sub? The next pic has antenna on it somewhere. Can I plug my antenna adapter in it for my HU?
