Realized this morning my ONSTAR / Phone antenna is missing. Any idea how much for a replacement ? Looks like it screws in doesnt look like it was broken off

Is the whole pod missing or just the actual antenna part itself?

Just the antenna

Jon how big a job was it to move yours from the rear window to the roof? It looks so much better.

If it's just the antenna it should be a cheap replacement. I'd probably just go back to the dealer or check eBay.

coolcat: If you are talking about my CTS-V, the antenna on the roof is actually a XM radio antenna. I hid my Onstar antenna behind the rear window. For the silver CTS, I did the same thing, but stuck a dummy antenna on the roof. :)

Sorry Sigma_1966 I didn't mean to hijack your thread, I just happen to be in the same boat and I thought that instead of buying a replacement antenna that there maybe an easy way to go to the 06/07 roof mounted style antenna.

No problem
