How to Identify BMW Navigation Main Unit Model Type

As early as the 1970s, BMW developed an optical navigation system that uses light spots on a transparent map to display the location and route. However, it was not until 1994 that the world’s first car navigation system was installed on the E38 as an optional device. Since then, the control unit responsible for the navigation function has been installed in the main unit.

The navigation main (host) is responsible for:

Calculate vehicle position from satellite signal

Process the transmitted CAN information (e.g. vehicle sensors, ACSM)

Navigation map

Route planning

Route guidance

Route guidance map.

 

The car navigation system can not only guide the driver to the destination faster and more comfortably, but also provide extensive and easy-to-use functional support in various driving environments.

Since BMW released ID5 in 2015, the updated data of BMW maps have been released according to the market size four times a year for the larger market and once a year for the smaller market. The roadmap in the updated data changes as much as 15% per year.

 

Depending on the model year and configuration, the host control unit equipped in each model is also different, and different hosts have their own dedicated navigation map data.

 

Every time we push the map update package, there are riders who don’t know how to choose the map update data that matches their own car because they don’t know (or don’t) query the version type of their car’s map data. So today we will do a simple science popularization (in the next issue we will have a systematic overview of ID1-OS8).

To determine your host type, please go to Navigation-Settings-Update-Version, check the characters in front of the map version number to ensure that you can get the correct update package to update the map data on the vehicle!

As shown in the figure above, the word “EVO” before 2017-2 means that the car is equipped with a HU-H2 host, and the navigation is EVO Road Map, which should be updated with EVO 20xx-x data. As far as the current mainstream models are concerned, roughly we can divide them as follows:
