: XM radio kit

01-03-07, 12:33 PM
I think I've seen some threads where early production STS did not come with XM tuner, and people were asking for a solution
GM just released kit for 07 models SUV's wich work on the same gm_lan system as sts
however, I checked pins configuration,they are a little different, but can be reconfigured. I called friend of mine at GM tech support, and he confirmed that this tuner would work on STS
part # should be 178011509 but one more time. this package was originaly made not for STS
hope this info will help
