Bought new Toyota van, and I know there's meant to be two wires to twist together for the electric antenna, which my van doesn't have, and one of them is the turn on for the factory amp anyways.
But since I put my new heady in and not connected the other 'antenna' wire the reception sucks.
Aerial built into the glass sunroof, wondering if I just got a crud aerial, or would the other antenna wire be for a signal booster or similar?
