Blaupunkt San Marino SQM 20 from ’89, perfect for your late ’80s, early ’90s classic

We have extensive experience in both digital and analog electronics (see our About Us page). This expertise allows us to restore and upgrade radios—even when schematics are unavailable—by applying our broad understanding of electronics to reverse-engineer the circuits. Our skills enable us to work on radios from any era, ensuring quality results in every upgrade.

In every upgrade or repair, we use high-quality, durable components to ensure a long-lasting result. Our latest PCB for Bluetooth modifications is designed to be compact and resilient, fitting seamlessly into almost any radio model. Each installation also includes a custom-made ABS bracket to securely mount the circuit, guaranteeing reliable, lasting performance.

As car enthusiasts ourselves, we deeply value the authenticity of classic designs. Our Bluetooth modification is completely invisible—no extra buttons are added to the device. We retain the original audio components, replacing only what’s essential to maintain functionality, ensuring that the device looks and sounds just as it did back in the day.

VanBrewer’s upgraded radios are designed to be free from disruptive connection and disconnection sounds. Have you ever bought a cheap Bluetooth speaker, only to be greeted by loud spoken instructions in broken English? We believe that has no place in a classic car! That’s why all of our upgraded radios are crafted to operate seamlessly, without any intrusive sounds.

We take reliability seriously. After each repair or Bluetooth conversion, we put the radio through a series of extended tests to confirm it’s in top working order, so you can enjoy uninterrupted use in your classic car.

We’re confident in the quality of our work, which is why every radio we convert or sell comes with a standard 3-month warranty. And of course, if your radio encounters issues after the warranty period, we’re always here to help. We value our customers and are committed to providing ongoing support.
