PAC OS2 will work for you great.  You will need an external speaker for the OnStar to be heard, unless you want to get really creative.

Oh I forgot, you'll need a Chime module if you want to keep the door chimes, and seat belt, low fuel, etc....I think it's a CM1, but not sure about the part #.  It's not necessary but you won't get the chime each time your low fuel light comes on.  May not be a problem, the light will still light up but no warning tone.

all i need is the power for it and the onstar how would i hook the onstar back up with a seperate speaker? and i just need the power cause im running all new wire and new speakers and amps2003 Chevy surburban

in order to maintain the RAP feature you'll need a data module of some flavour.......Kevin Gerry
