Broke the XM radio/OnStar antenna cover...Yes, I'm an idiot!

Yeah so I was clearing the snow off the top of my 2008 Sierra when, POP! I broke the cover for the XM radio/OnStar antenna in half. Needless to say I was seeing red for about 15 minutes...

The dealer wants about $400 to fix it ($240 for the part and about $150 labor). Honestly, I'd almost consider it but I'm worried about the quality of the work.

That being said, in doing some searching, I found the part, OEM on ebay for $70, shipped. I'd be crazy to buy the one from the dealer. Even the one on GM parts direct is $100 less. My only concern now is doing the job myself.

Has anyone had their headliner down at all. It looks like I should be able to just drop the front of it. I have a sunroof which may even help matters as I'd have another angle from which to get at it.

Hey thanks for the insight folks! I think I'm going to try the install myself, in the spring of

I'll take pics and put it all on a thread.

I'll keep you posted...

Any other advice welcome!

Yeah, in searching I found the same thing. Several different part numbers and parts. The one in your pics, in fact, is different from the one I ordered. Mine, from what I've seen in the pics has 3 wires.

From what I understand, my antenna is for the XM radio as well as the OnStar.

What I ended up doing is going to the dealer and getting the info (and price) on the correct part for my truck, then, you guessed it, using the inter-webs to see what I could come up with. I found the part, OEM GM part, on ebay for $70, shipped. The dealer wanted $240!

Now, I am one to try and spend my money locally when I can but $170 difference?! Forget it!
Just an update. Replacing that antenna is a breeze! Anybody have any questions, let me know...

Thanks for the help folks!


The dealer wanted like $400 for the whole job, parts and labor. I got the part on eBay for $

Another example; I got into a little "fuss" with a late model Silverado and we clipped mirrors. Both the top and bottom covers on the mirror shattered. Other than that the mirror and all of it's functions were perfectly fine.

I went to the dealer (I usually start there for info and true part numbers) and was told I could buy the top cover but the bottom cover only comes with the whole mirror assembly. I have the SLT. It's a loaded, power mirror with heat, dim and power fold. WHOLESALE, it was $360. It's a crock! The bottom cover comes off the same way the top comes off. It's a scam they don't sell the bottom cover separately.

I found the whole mirror assembly on craigslist for $40 and just bought the top cover at the dealer (the top cover on the one from craigslist didn't match).

Point is, like Hdjoe said, do it yourself. F the dealer unless you have to. I get the feeling I'm preaching to the choir
