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 are positioned in the following order (applies to structure week 200946): 

1. Infotainment control module (ICM)
2. Phone module (PHM)/ Bluetooth phone module (BPM)
3. Audio module (AUD)
4. Multimedia module (MMM)
5. Remote digital audio receiver (RDAR) (only USA market)/Digital Audio Broadcast Module (DABM) (applies to all other markets from and incl. structure week 200846)
6. Integrated Audio Module (IAM)
7. Accessory USB unit (AUU)

The control modules should be positioned in the following order : 

1. Infotainment control module (ICM)
2. Integrated Audio Module (IAM)
3. Accessory USB unit (AUU)
4. Phone module (PHM)/ Bluetooth phone module (BPM)
5. Audio module (AUD)
6. Multimedia module (MMM)
7. Subwoofer module (SUB)
8. Remote digital audio receiver (RDAR) (only USA)/ Digital Audio Broadcast Module (DABM) (applies to other markets)

If the minimum configuration of control modules on the MOST network in the car is used, the following control modules are connected:

• Infotainment control module (ICM)
• Integrated Audio Module (IAM)
