If you have the steering controls its to the left of the band button.

 

That's weird, I thought they all had it..... I would have to say answer no to the onstar and yes to Bose....? I'm not sure it matters as far as install goes. The adapter may be different though.... let us know what you find out. Never heard of this.

 

on the 06 trucks when they went to the goofy option package configurations, onstar was optional on even the highest-end trucks.

On 05 and earlier if you got a fully loaded truck with the heated bucket seats etc.. it automatically came with onstar. 06-07 classic you could get a fully loaded truck with bose, heated buckets, auto climate control etc WITHOUT onstar.

07.5+ gmt-900 they made onstar standard in every trim-level, even the base model work trucks.

 

^^^x2 my truck has no onstar

 

like wise no onstar everything else tho (well ok cloth seats, which was ggod with me)

 

since i don't have onstar, the government can't keep track of me, right?:rof

 

paranoid



maybe but we are watching you:rof

 

Have leather and loaded but no XM or OnStar

 

The trucks with a short antenna on the roof have OnStar-- the flat box on the roof right side is for the XM. Newer vehicles combine them into one antenna.

 

mine has the short antenna on the roof and when i change from am to fm it also has 2 xm options. but i'm not sure how to set up for xm, but i don't need to...
