How do you turn off car phone? Every time I start the car it makes beeping noise

Greetings, I am assuming you have an old analog cell phone in your center console/armrest. The best advice I can give you is to find the power source to it or fuse and unplug it. Any BMW Specialty shop can do it for a very minimal fee (no more than 0.5 hrs. of labor if any at all) Keep in mind this is not uninstalling it just removing the power that runs it. I hope this helps, Kind regards, Stephane Grabina BMW Excluservice Rocvkille, MD 20852 www.bmwexcluservice.com
