Found this on audiform - this is what I did http://audiforum.us/cables-adapters-...rns-e-gps.html fyi, you buy a, say, 6 foot fakra / fakra extension, attach it to the lead from the sharkfin GPS antenna which you will find at the OnStar module under the front pass footwell (you will have to remove the glovebox, and part of the doorsill, and pull up the carpeting to get to the OnStar unit). Remove the OnStar unit as it is dead weight anyway. Run the Fakra/Fakra lead to your RNS-E unit. Voila. Mine works perfectly. I don't recall if the Fakra/Fakra extension is male/female or female/female or male/male - you'll have to figure that out when you check the antenna lead going into the OnStar module. Good luck.
