The Ontario CTS Club Discussion, Antenna in Cadillac Clubs, Local Chapters and Regional Forums; Realized this morning my ONSTAR / Phone antenna is missing. Any idea how much for a replacement ? Looks like ...
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.
