When a control module is added to the MOST network, it should be placed in the correct order on the network to make it easier to fault-trace the control modules.

If the control modules are connected in another order, this does not effect the function of the MOST network, but fault-tracing will be more difficult.

The control modules should be placed in the following order (applies to C30, S40 and V50): 

1. Infotainment control module (ICM)
2. Multimedia module (MMM)
3. Remote Digital Audio Receiver (RDAR)
4. Audio module (AUD)
5. Phone module (PHM)/ Bluetooth phone module (BPM)
6. Integrated Audio Module (IAM)
7. Accessory USB unit (AUU)

The control modules should be placed in the following order (applies to the C70): 

1. Infotainment control module (ICM)
2. Multimedia module (MMM)
3. Audio module (AUD)
4. Subwoofer module (SUB)
5. Remote Digital Audio Receiver (RDAR)
6. Phone module (PHM)/ Bluetooth phone module (BPM)
7. Integrated Audio Module (IAM)
8. Accessory USB unit (AUU)
