Same exact thing when I installed my Pioneer Avic unit in my '07 gxp. The retention kit is for your door chime and onstar retention. but you will lose the date/time on the DIC. I believe the 12v constant to the DIC is fed through the radio, but the metra/scoshe harnesses eliminate it. Im sure you just have to find which pinout is for the 12c constant to the DIC and wire it up but I haven't messed with that yet. I'm just living without if for now.
