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.
