Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Integrated Audio Module (IAM) (2007-2014): Design: Antennas
The integrated audio module (IAM) is connected to an AM and FM antenna system. This consists of a main antenna, an FM sub-antenna and an AM antenna. The antennas are connected to an antenna amplifier. The antenna amplifier has two channels: one for the FM main antenna and the AM antenna and another for the FM sub-antenna.
Both channels are connected to the integrated audio module (IAM) via a coaxial cable.
The connection for the sub antenna is used to supply power to the antenna amplifier. If the Multimedia module (MMM) is in the vehicle (does not apply to the USA), the sub antenna is connected from the antenna amplifier to the Integrated Audio Module (IAM) via the Multimedia module (MMM).
