I have a Sirius Onyx setup that I want to install in my 2011 1LT. I cannot
seem to locate the fm modulator that will fit the antenna. Does anyone
know where I can locate one.


Thanks,
Duncan

 

I'm not sure if there is a direct fitment fm modulator for gm. If you buy the sirius modulator, you can go to radio shack and buy adapters for both ends. If I remember correctly, it cost be and extra $10-$15 for the adapters.
