Hello, I have a 2008 Corvette with nav, but no XM.

The link above says "OnStar and XM Satellite Radio standard on all models"

I have OnStar.

Is there a special code/button combonation to get the XM to show up on the radio?

No antenna on roof, from what I have read, the XM antennas in the Corvette are in the side view mirrors. But I don't really know for sure.

When the XM box is plugged into the NAV unit, then it will show up as a source choice on the screen. If the XM box is not there, not plugged in, or not powered (12v) then it will not be a choice on the screen. The XM box is located behind the waterfall (the real waterfall) in my Vert. I'm not sure where it is located in a coupe. A coupe owner will chime in, then you can look and check it.

I found it! The XM box is located in the rear right above the drivers side wheel well, I had to pull the carpet back to see it, now for the trouble shooting, power etc. Thanks again.
