Purpose and function in the vehicle

The presented navigation module is the central element of the satellite guidance system in the BMW 7 Series E66. It is responsible for:

• processing data from the GPS antenna and maps,
• cooperation with the central display and system controller,
• communication with other controllers via the vehicle bus,
• coordination of navigation functions within the factory infotainment system.

By using an original module, software and communication consistency with other controllers is maintained, which reduces the risk of errors, fault messages, or integration problems.

Benefits of using an original BMW module
