The Hamburg MR21 is the same radio as the London MR21 but includes Ari traffic information. A top-notch radio, which Blaupunkt had positioned just below the absolute top model called Bremen. This type of radio was expensive and was therefore mainly used in vehicles of a higher price range such as cars from Mercedes, Jaguar, Ferrari and Porsche. The Autoreverse cassette-player works, but it could use a new belt after 38 years. Nice sound, 4 outputs, 4x7 watts output power. Radio works well. The light also works. The radio is completely original, undamaged and complete. - Type: Blaupunkt Hamburg MR21. - FM, Long wave and Medium wave (AM) - Year of manufacture 1982 - 12 Volts - Stereo - ARI traffic information (no longer exists) - 4x7 Watts output power - 4 Speaker connections - Tone control and balance control - Mounting dimensions (wxhxd) 179x50x170 mm - Front dimensions (wxh) 190x60 mm - Made in Japan
