hey guys, sitting in computer class and i just figured this out because i pretty much have nothing else to do right now. I bought my car yesterday, and the stubby antenna on mine is on the back side of the roof, while many others i have noticed have their antenna on the front side of the roof. I personally think it looks better on the back, but is there any reason for this? Let me know what you think. Thanks

i think the one on the front is for onstar, while the one on the back is for XM

mcphatty i think you're right... mikekoz, which options did you get (xm, onstar)?

i have both of those options, and only 1 stubby antenna, i think gm got it so they both run off of the same antenna, correct?

i think the one on the front is for onstar, while the one on the back is for XM


correct and I think for 06 they combined them ..(that could be a dream though...someone who does less drinking confim ...lol)

you might be right about 06 models. i have an 06 but didn't get xm or onstart so i wouldn't know for sure, but my dad works at the dealership in services so gimme a few minutes to call him and i'll get 100% fact.

k, but it's weird that mine's in the back... hmmmmmm

yeah for 06 they should both be combined into one back fin type antenna

does it have to do with sunroof or not, my xm antenna is in the back and I have a sunroof. If that helps

nope I dont think so ...xm was allways at the back with a fin style antenna ...however onstar was a different antenna at the front (ugly) however I beleive for 06 they are mixed into one fin style antenna at the back (where xm is allready)

hey.. maybe you're right. I have a sunroof too, and the one or two i saw didn't. :cssNET:

In 06 they combined the antennas :cssNET:
