I believe that info sheet may be wrong -- to my understanding SRT OPTION GROUP I is "standard" on the SRT8 challenger and the only option group available is SRT OPTION GROUP II. This is per the leaked Chrysler documentation PDF (back on 5/12/08) found on another Challenger forum. This would make sense because the major pull of group I was the U-connect in the rear-view mirror, which is part of the MyGIG system now instead.

I might have to double-check with my dealer, but he had only mentioned group II at the time of ordering and that's all I can find in the chrysler PDF. group I seems to be standard. Anyone able to chime in on this either way?

--EDIT--
Further looking into it, the Electronics Convenience Group (Package AFC) on the R/T includes Illuminated cup holders/U-Connect

since that group is usually "Standard" on SRT8s anyways, that again makes sense. There's no mention of SRT OPTION GROUP I in the Chrysler PDF, only II (Package AY2).
