      The original factory antenna connection literally pulled out of the old radio as I removed it. This part is absolutely necessary as an extension as well as an adapter kit to the new radio installed.

      Tried it, didn't work. Problem was it doesn't work for my vehicle but will work gm or chevy vehicles. Unfortunately things like this don't work for semis.

      I purchased this antenna adapter as part of the install of my iSimple FM Transmitter. I had Geek Squad install the adapter and it works great. No complaints.

      Not a very good connection. Radio stations that played perfect with factory radio now has static. But it's the only adaptor that'll fit for my car
