My D3 was stolen, so I'm upgrading to an 8000. I need to find out if the wiring harness and install kit that i already have are compatible. I have never done a stereo install, so this is likely to be a challenge, so any help you can give me is incredibly welcome. I have a 2003 Nissan Xterra, so if anyone knows what exactly i'll need to install my 8000, please let me know.
