The stock antenna is proprietary, I believe, and you will need an aftermarket one for plug compatibility. But, I'd try it before getting an aftermarket antenna.
There were two options. A cheap one or a $130 one. I was hoping I could get the cheap one since I didn't have the premium stereo. Guess I'll be calling up Crutchfield. Thx.
Will do! Just added an avi.
