MOST bus: Headunit
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
The headunit is the interface between the data buses MOST and K-CAN. For the rest of troubleshooting (read fault memory, etc.), the associated control units must be selected at the BMW diagnosis system. One of the following head units is fitted in the vehicle.
- Radio 2, (RAD2, RAD2 gateway)
- Central Headunit and Multimedia Platform, (CHAMP-BO, CHAMP-GW)
- Multi Audio System controller, (M-ASK-BO, M-ASK-GW, M-ASK-NAV)
- Car Communication Computer, (CCC-ANT, CCC-ASK, CCC-A, CCC-BO, CCC-GW)
- Car Information Computer, (CIC, CIC-GW)
Distinction between the head units
Unlike CIC, M-ASK and CHAMP the CCC has two slots at the front. This external characteristic can be used to distinguish the CCC and M-ASK.
