I have XM in my car now and I want to get rid of the factory mounted antenna thats in the rear fender. I can unscrew it, but I wannt get rid of the mount and put a cap in its place. And sooner or later just delete it entirely. Anyone know how?
 
 
THe mounting on the antenna should be screwed into the fender.  I believe u just have to get some pliers and play around with the nut on the inside of the fender.
