    i wired a DIC into my 1999 grand prix gt and the only info that those things pull from the OBD is the fuel pump informations which it uses in sync with you speed and rpms, to calculate everything it needs

    Install in my 05' Malibu

    I am taking the leap to remove my Factory Headunit and replace it with a touchscreen. I would really like to keep the DIC usable. Options are: Relocationg, Figuring out how to control Via Carpc, Metra adaptor kit. I am building a bezel for my 7" Touchscreen to fit directly into the dash space for an OEM look, so Single din + Metra kit is not really an option. Relocating may be the only solution, but it seems like a wiring nightmare. When I saw this thread I got excited thinking maybe someone had figured a way out to use the pc to operate basic functions of the DIC.

    Has anyone gotten anywhere with this? I'm not nearly skilled enough to program an interface, or I would be all over this.

    Thanks in advance for any input.
