Phone Module (PHM) - Vehicles With Infotainment Control Module (ICM) [2009-2017]: Design: Antenna
A separate antenna belongs to the telephone. This antenna contains a telephone antenna and, for vehicles prepared for Volvo On Call, a GPS-antenna as well.
The phone antenna is directly connected to the phone module (PHM).
For vehicles equipped with Volvo On Call-functionality, the GPS-antenna is directly connected to Phone Module (PHM). This is due to the GPS-position not being available from other control modules in the vehicle.
