In principle, the structure of the CHAMP corresponds to that of a personal computer. In a similar way to a PC, the CHAMP contains:
- Processor
- Working memory
- Other peripherals
The following applications are stored on the memory card (16 GB with navigation system):
- Navigation software (application software)
- Navigation (map data)
- Voice processing system
- Contacts (database of names and addresses)
The head unit is connected to the diagnosis connector via Ethernet. This means that in service mode, map data for the navigation system can be loaded via the ISTA/P programming system as standard.
Because of the extended functionality, the connections on the rear of the CHAMP have changed.
