After installing a aftermarket stereo head unit -my radio reception was not like it was with the stock system. I tried all kinds of home-made antennas and nothing ever worked since the factory one did not work either. I was extremely frustrating considering the main reason for switching over was to have HD radio which worked but not that great. After reading many reviews I final went onto eBay and bought a Dakota Digital AM/FM Hidden Antenna for $35. Many people claimed it to be the best for people that don't want a exterior antenna like motorcyclist and custom cars. I was surprised to find that not only did this antenna do as it promised, but I also got AM radio which is something the stock didn't do that well either. Anyway, it works great and highly recommend it if you are switching over to a aftermarket stereo head unit to use a iPod or HD features.
