Got the used 15' Impala antenna installed, color matches and I feel it looks great on the car.
Had one issue, the AM/FM cable is busted (it's used so I was expecting something to not work), OnStar/XM cable works. I pre-tested the antenna prior to removing the old one.
So I plan to find another one that works and replace the cover.
Replacing the antenna is a very simple process. Tools needed, 10mm socket or ratcheting wrench and nylon or plastic trim removal set. If you have to swap Fakra connectors, tiny flathead screwdriver and pick tool.
1) Pop the 3 retaining rivets free on the head liner at the rear windshield. Don't remove them from the liner, they have plastic washers holding them the the liner. I stopped here at trim removal because it offered enough clearance to access the two wire connections and the antenna retain bolt and clip.
2) Next, break free the connectors from the body frame (they have retainers holding them to the body). Now you can separate the two wire connectors.
3) Use a socker or wrench to remove the antenna bolt and retainer clip. Carefully remove the antenna base with clear plastic retainer.
4) Check stock antenna fakra connector with the new antenna and swap connectors as needed.
5) Prep the roof for the new antenna, make sure the clear plastic retainer is on the base. Go inside and bolt it back in with the metal retainer.
6) Connect the wires back together and connect back onto the body frame. Pop the 3 head liner rivets back in place and your done.
