Handy customers experienced with working and tinkering on classic cars can install a radio by themselves. All others we strictly advise to have their vintage radio installed by an experienced mechanic / electrician / local garage. Our installation kits contain the parts and instructions needed to install a radio in a factory original prepared car. In case your dashboard aperture / mount has been changed by previous owners over the last 40 -50 years you might need, or have to make, different parts to make the radio fit properly.

*1.5 years (18 months) European / US warranty (See About Us / FAQ). In the rare case that a reliable Blaupunkt transistor radio stops working you send it back to us for immediate exchange (in case a comparable unit is in stock) or repair. The radio is sealed before shipping with a unique numbered security seal which cannot be tampered with. If this seal is damaged / broken the warranty will be void.

Attention: Blaupunkt Frankfurt stereo radios built between 1969 and 1974 feature an additional ‘stereo’ lamp behind the scale-dial. The lamp is supposed to light up when a stereo broadcast is detected. For this the radio needs a perfect antenna and a perfect earth / ground contact of the radio AND the antenna. The ‘decoder’ which operates this tiny lamp has in many cases lost its function over the last 40 – 50 years. This can not be repaired because the part is not available. In some radios the ‘decoder’ still works, in others it does not. Therefore, functionality of the decoder and the lamp is excluded from warranty.
