wanting to take out stock stereo

I want to take out my stock stereo in my 2003 Malibu but I need a wiring harness. I don't have the RDS(think thats what it is called) version in my car. Scosche say I need a gm09 but they have a gm11 for 2000 gm models and up, it lists the malibu as one of the cars it works in. I need to know if this one will work in my car. Does anyone know?:banghead:

just buy it and try it...if not, then return it....

if you want to use american international kits you will need gmk420 dash kit, gwh22 wire harness, and gm6 antenna adaptor

and if you want to continue using the remote locks and alert chimes you need a special harness that connects to your stock radio (which is sitting in my trunk hooked up) and a little speaker for the alerts. $70.
