All them green wires are usually the speakers.
Therefore, I don’t think you have an amp ?

The blue plug on the new unit is for remote so will need to get a plug to fit
Once connected what will this do

its the blue and white striped wire that is your remote out you will need to get a pin that matches your aftermarket plug attach the wire to it and put it in the plug D4 GS let the retro fit begin
