Ok my car dosen't have a built in antenna and when i installed my aftermarket headunit i put a aftermarket antenna in with it, and i can barley get any radio stations. The antenna is attached to the back of the headunit inside my dashboard. I called my car audio shop and they didn't know anyother options i could try out. So i'm hopeing some of you guys could help me. Any suggestions are greatly apprciated. Thanks a lot for looking =]
