my power antenna has been broken since i bought the car and my radio only gets 3 stations, so in doing a little research i found out about the antenna in the back window. last night i pulled apart the interior of my car and traced the wire that was attached and found the the plug was different then the plug on my radio, so i went to a car audio place to get an adapter and for 7 bucks he hooked it up and now my radio gets just about every station in the area. next is to have the hole filled from the power antenna. very much worth the money.
