BMW Information / BMW Radio Service Mode Settings

List of procedures that give access to BMW radio service-mode settings for making base radio adjustments or for visual checks. These are often used in the factory or dealership for the initial setup for the vehicle locale. Radio settings will vary between models and this list does not cover all known models. Play with these at your own risk!

BMW uses several different manufacturers of radios. The most common are: Alpine, Pioneer and Blaupunkt. On earlier vehicles these manufacturers can be found: Bavaria, Becker and Phillips.
