I am planning to replace the factory radio in my TDI Package 2--no automatic climate controls. I have the 6 disc changer model with satellite radio option mounted in trunk. There is no digital amp mounted under the seat. I would like to adapt the AM/FM antenna cable to the aftermarket radio and don't want to remove the factory unit twice just to verify what cable I need to buy. I have seen a single connector adapter cable to standard Motorola connector, dual one piece connector (one for FM and one for AM) adapter cable to standard Motorola, and two single adapter cable connectors to standard Motorola. Does anyone know what type I should have? I have had no luck finding images of the back of the factory radio nor is the Bentley service manual much help. Thanks for any advice.
