First, if you have an intenal antenna I think it would be silly of you to put a hole in your car for an external antenna.

Second, I went to Honda about the antenna's and it's a lot of money $100+ if you want the whole unit including the amplifier.

Third, if you simply get the antenna and not the whole unit with the amplifier you will have a drastic reduction in receptioin.



I say eff the antenna, spend your time and money elsewhere.
