I love what your doing with the site!!
I am looking at buying the D1 and was wanting to know what I am getting into as far as what I will need to install. I have factory XM and Onstar with steering wheel controls. I would like to retain all of them if I can. I am not sure what modules I need as far XM adapters, Onstar adapters, and what ever is needed to hook up a dvd player.
Thanks
