For restorers who treasure authenticity but still want modern functionality, the Aurora Design FMC-3.2 is a noteworthy solution. Though technically marketed as a “FM/Tuner Conversion Board,” its value in classic car radio upgrades is widely appreciated—and for good reason.
Seamless Integration into Original Radios
One of the FMC-3.2’s major strengths, as reported by users and conversion specialists, is its ability to slide invisibly into vintage AM radios. According to its product description, the FMC-3.2 “opens up a new world of possibilities for early automotive AM radios. With the FMC-3.2, any AM radio can be made to receive FM stations, and provide an auxiliary input for MP3 players, satellite radio, etc.”
Owners often mention that this conversion retains the factory radio’s original knobs, bezel and dial—so on first glance your dash looks completely original. One installation story on a 1950s Ford F-100 noted:
“The FMC-3.2 is very small and unobtrusive… it can be mounted entirely in the head of a 1953-1959 Ford F100 radio.”
That kind of capability earns strong marks in the restoration world.

Modern Features Without Compromising Style
While the FMC-3.2 keeps the external appearance vintage, inside it brings modern capability. The description references “selectable VOX Auxiliary Input and twice the output voltage” compared to earlier versions. This means you can add your phone, MP3 player or satellite tuner without sacrificing original dashboard authenticity.
Forum users also highlight how the upgrade dramatically improves station reception and clarity compared to stock AM-only units. One commenter summed up their experience:
“The result is a radio that looks exactly as original and operates exactly as original (only better).”That “only better” phrase captures the lift in performance while preserving appearance.
Reliability & Build Quality
Another frequently cited benefit is the build quality and engineering behind the unit. From conversion-specialist sites:
“Your original radio was built for quality and so is the FMR-3.2!”
While that quote is about the FMR line (which shares the same engineering ethos), it reflects Aurora Design’s overall commitment. The FMC-3.2 inherits that pedigree—making it a trusted choice rather than a cheap “hack” solution.
Why Enthusiasts Recommend It
-
Keeps factory look intact while delivering FM and auxiliary input functionality.
-
Installs into original radio chassis without modifications—controversial dash cutting avoided.
-
Enhances listenability: better tuning precision, quieter electronic background, modern audio compatibility.
-
Works across voltage types: supports either 6-volt or 12-volt systems, positive or negative ground.
Considerations
As always, when integrating into a vintage radio, the existing tuner mechanism, control knobs and chassis condition matter. In forums, users note that a complete refurb (cleaning, lubrication, calibration) of the original radio often precedes the conversion to get optimal results.
Additionally, while the FMC-3.2 gives you FM and AUX, if you’re seeking full modern features like Bluetooth or USB playback, you’ll need additional modules or conversion beyond this board.

If your restoration calls for the original radio look and function—but you also want to tune into today’s FM stations or plug in your phone—the FMC-3.2 delivers in a quiet, sophisticated way.
For purists, this conversion is one of the smartest moves: retain the vintage exterior, upgrade the inner workings, and keep your classic ride both authentic and functional.
