Is the onstar antenna acessable to use adapt for cell phone use? Two reasons, Onstar outrageous phone rates and my insurance company won't give me an additional discount for the auto theft tracking I get only a 5% discount for the kill switch I had installed.
Back to the question, has anyone tried this? If so let's hear on how & the outcome. I get some crappy reception in some areas of Las Vegas(Sprint PCS )
Thanks
