When I tried to order the member brace set, I was told that it was out of stock, so I installed only the helical short antenna that I ordered.
It's much shorter than the original one, and I'm satisfied with the fact that it also includes AutoExerogo.
I think the good thing about it is that it's available at dealers, so you can easily order it, and you can install it without any worries.
