| I bought my first BMW a couple months ago. It is a 2001 540i six speed.
Sports package/winter package and Navigation.
The main problem I am having is that my navigation screen opens and closes multiple times when I unlock the car and when I start the engine. There is a cassette deck behind the nav screen, but its 2005 so it dosen't get used. Can anyone tell me why the screen does this, and how to stop it? |
