Robust, easy to use, and uncompromising in terms of quality: these are the features that drivers of commercial vehicles expect from a radio. The Blaupunkt Heavy Duty Line meets these requirements in both the 12-volt and 24-volt segments. A CD drive protected against shocks and vibrations allows for unrestricted music enjoyment even away from the roads. All modern USB media can be conveniently connected and played. Thanks to fewer and larger rubberized station buttons, operation is always intuitive. The thoughtful design extends to the details: saved radio stations remain intact even when the vehicle battery is disconnected for maintenance.
