I found the following in a post on the saturn aura forums;
“
Re: AP3 versus AP8 code?
RPO AP8 is a "Remote Starter Prep Package," meaning the car is wired for remote start, but it isn't enabled. Enabling it means purchasing a kit (2 fobs, instructions, and a unique code) from GM. The dealer tech then calls the TechLink Center w/ the code and VIN to get a VCI to reprogram your BCM.
If your vehicle has remote start (AP3 - I think all '07 XRs did) and it works, what's your beef? Just that the RPO code doesn't show up? What codes
do show up? Sorry, I haven't been on the Aura forum in a while, so I'm not up on any back-story.”
hopefully it helps a bit
