I actually am a manager of car audio for Circuit City. the part is DEI SIR GM1. I have installed these in several trucks and suv's they work great. up to 06 models but no luck on 07's. I tried to put one in a 07 tahoe last week and it wouldn't work...have not tried it in my own 07 vette because I get XM for free..

The SIR GM1 does the trick, including in the '07s(I installed one in a friend's '07 coupe). For the coupe the XM module is over the left rear wheel well, just pull the carpet back. For the vert, it's a bit more work as the XM module is tucked away under the waterfall. However even that isn't bad to do as all it requires is removing a few bolts and a christmas tree pop connector.
I'm a recent convert to Sirius myself after years as an XM customer. I'll be installing the SIR-GM1 in my vert within the next week or 2.

If they are running an antenna about an hour. When we did my friend's he had an adapter to connect to the factory XM (does work, but reception isn't the best) and it took about... 3 minutes.

But I have no Sat button on the interface
I just called a reputable stereo company locally, and the 1st thing they asked me was if I had a "Sat" button on the radio's interface. I do not. He then said he needs to do some checking on this and I should call back tomorrow.
btw, fwiw, i have the in dash 6 disk CD changer.

To use the SIR GM1 what you need is a radio that can control XM. There are only 3 radios used in Corvette and I believe only the base model (1SA was it in '05?) didn't have XM as an option. The 6 CD changer can control XM therefore it can use the SIR XM.
The only question I still haven't gotten anybody to answer for me is if the XM harness is present in cars that don't have XM as an option. I *think* it is, but worry about that assumption because I know for a fact that only factory NAV cars get the GPS antenna installed.
Pull that carpet back over your right rear wheel well. You should see a tray or a couple of clips anyway where a tray would go. If there's an unplugged wiring harness in there you're good to go.

I think I mentioned above, it's under the waterfall. There are 2 pops to remove from where the trunk divider attaches to it, then there are a couple of torx-headed bolts on top and another pop on the passenger side. Then you'll see the XM sitting in a carrier under that.

When I went to Cruchfields to buy the unit, they asked for vehicle info. when I put in vert 07 with Bose they daid the unit would not work. Is this correct or do they just not have instructions for this. The car doesn't have Nav.
