I have an 04' (see sig)... but it is the "base" package, roll up windows, manual door locks etc... does this have anything to do with the DIC? I was reading another thread and it said something about business and personal DIC... my DIC only shows trip mileage, odometer and hours... does the "base" package have the inst. MPG, trip MPG, etc. features?? or am I just in "business" mode?
