First, you need to find the location of your phone's navigation stand. In general, there is a stand at the bottom of the center console in the BMW car to fix the phone to it. After determining the position of the bracket, unfix it according to the fixing method on the bracket, which may require pulling the bracket or prying the bracket until the bracket can be easily removed from the console and the phone can be removed from the bracket. If you are still in doubt, check the BMW manual or consult the relevant car repair specialist.
