My STI8 came with STI7 manual, the bug eye line drawing on the cover gave it away. Stereo fitted in car also not featured. Apparently early 03 models were being sold before the correct manuals were available. I was able to swap out with later delivery batch of cars. Correct Pt. No. is A1860GE. Did you get the right one?

 

just picked up my my02 and it had a my03 manual, could swap if you like!
