Integrated Audio Module (IAM) (2009-2013): Design: Antennas
Integrated Audio Module (IAM) is connected to an antenna system for AM and FM. This consists of two FM-antennas (FM1 and FM2) and an antenna for AM.
For C30 and C70, FM1 is also used as AM-antenna.
Antennas are connected to one or two antenna boosters depending on vehicle model.
Integrated Audio Module (IAM) has two channels, one for FM1 and AM as well as one for FM2.
Both channels are connected to the integrated audio module (IAM) via a coaxial cable.
Connection for the FM2-antenna (sub-antenna) is used for voltage feed of the antenna booster.
