I was in Advance Auto today picking up a spark plug gapper, when I came across this antenna. Considerably shorter than stock. Material is aluminum and carbon fiber. Antenna comes with several threads to adapt to the car.
Price $13.00.
Reception on XM, AM/FM, and Onstar are functioning fine with no issues.
Reception is the same as with the original whip antenna. no signal loss or whatever.
Its threaded inside and comes with three screw type adapters, one of which fits the Cruze's antenna base.
I got it from a local auto accessories shop for about the same price as the OP's.
anyhow, here are pix of the stubby antenna I installed
it has a small gap where the base and the stub antenna meets but it doesn't bother me, plus it has totally no effect on the signal reception.
Well I was going to do a video how to but I'll do my best to explain. First grab antenna, then twist counter clockwise about 20 times. Store in a safe place.
Please note, I don't care for radio or xm or onstar. Do at your own risk.
