This is the Blaupunkt DUBLIN412 Heavy-Duty Receiver with Bluetooth, designed to work on 12-Volt electrical systems. Perfect for construction equipment, heavy duty trucks, buses, and other commercial vehicles. Functional infotainment in a new dimension. Resilient, easy to use and uncompromising in terms of quality: characteristics that commercial vehicle drivers in particular expect from a radio. The Blaupunkt Heavy Duty series meets these requirements – in the 12 volt segment. All modern USB media can be conveniently connected and played, and thanks to fewer and larger rubberized station buttons, operation is always intuitive. The well thought-out concept extends down to the smallest detail: stored radio stations are retained even if the vehicle battery is disconnected during maintenance work.
