To transfer a route to your BMW car, you will need a USB stick.
On this USB stick you will first need to create the following directory structure:
- BMWData/Nav (2 folders total)
- BMWData/Navigation/Routes (3 folders total)
After that you can use the MyRoute-app Connector and select "BMW Car" as the preferred device to export to.
Once the route is transferred, you can place the USB stick inside your car and use the media system of the car to import the route from the USB stick.
