Aurora Design  THIS IS IT -- the revolution -- the Stereo heard 'round the world!
Indeed there have been other conversions on the market.  The demand was there and we did our best to satisfy.  However a major downturn in quality sent us looking for something better, and as fate would have it a design engineer contacted us with just such an offer.  Click here to read the story behind this new stereo.
The new Aurora FMR-1 is so superior to the other products that the competition called us to voice their discontent!  Yes, that really happened!  Customers with the older versions have been sending us radios for an upgrade; other dealers have also switched to this product.  THE NEW AURORA FMR-1 STEREO RECEIVER HAS TAKEN OVER AS THE NEW STANDARD FOR CONVERSIONS!
Built in automotive plants in Detroit to OEM standards, and designed specifically for vintage radios, you'll find yourself enjoying your stereo vs. putting up with it.  If you've experienced those expensive "repro radios" or older conversions you know what we mean.  The tuning is rock-solid digital, yet it has the easy-to-tune "feel" of an analog radio.  No fidgeting with the controls to get the station you want; no drift that forces you to keep re-tuning it.  No surprise bugs and idiosyncrasies to make you second-guess if the radio was worth the investment.  And no smoke if you accidentally touch a wire to the wrong place -- the PCB is fully protected against any such abuse you care to give it.
So what exactly IS an FMR-1 Conversion?  Simple -- we completely disassemble your radio, clean and adjust the controls and tuning mechanism as needed, then replace the primitive components with a new PCB that contains an AM/FM Stereo.  In the dash it looks totally original, but turn it on and you'll be treated to modern sound with AM/FM stereo, an audio input, and (optionally) Bluetooth and USB interfaces.  Operation is the same as before -- pushbuttons, Wonderbar, Town & Country, Electro-Touch, Rotomatic, and other tuning designs will work on FM in the same manner as AM.  Band switching, input mode, balance, fader, and other functions can be controlled with the radio's original controls.  Of course if you have an original AM/FM switch, balance control, etc., these will be wired to operate as original.
A note about LED indicators:  The PCB includes a tiny LED indicator, used for initial setup and diagnostics.  Older conversions often included a larger dial-mounted LED (we didn't use them) that indicated if you're on a station, and rotated three colors like a Christmas tree for input mode.  Although the FMR-1 has provision for a dial-mounted LED, we do not install them.  It detracts from the original appearance of the radio, may be annoying to look at, and does nothing to enhance the stereo's performance.  In the unlikely event that troubleshooting is required, the LED inside the radio can be utilized.

Prices:  We try to make the pricing uncomplicated -- but radios, and the ability to service them, vary all over the place.  Please read all notes below.  Specifically, if your vehicle does not have 12 volts negative ground available, you'll need a voltage booster.  If your Wonderbar/Town & Country radio is a 1958 or earlier, it may require additional hardware.

FMR-1 Stereo Conversion price:

We would love to have a standard price for every radio, but car radios are not all the same.  Certain models require considerably more labor, and this has to be reflected in the price.

All-transistor American AM radios, manual or pushbutton (typically 1963 and later):  $385

Tube/hybrid manual/pushbutton/Rotomatic radios (1946 and later), AM/FM sets, early AM/FM Stereo (except 46-48 Lincoln as described below):  $400

European-made sets (Blaupunkt, Becker, Radiomobile, etc.):  $420*

(NOTE:  many American import cars were fitted with American-made radios.  Example, Volkswagens, Volvos, Triumphs, and Alfa-Romeos sold in the US have either Motorola or Bendix radios, and the US price applies)

Wonderbar, Town & Country, and other signal seeker sets -- MOST models:  $445.  See notations below.

  • Selector Bar, Wonderbar sets for Cadillac, Buick 1950-1958 (except 57-58 Eldorado transistor), 1951-57 Other GM, Studebaker, Packard, 1955-56 Mopar Electro-Touch:  $495

  • LINCOLN Radios:  1946-48, 1958-60, 1965 and later AM/FM: Add $50*

  • LINCOLN/MERCURY:  1956-57 Mark II, 1956 Lincoln and Mercury Town & Country:  $545*.  The GOOD news:  it is labor-intensive, but possible to convert the Continental Mark II's and other 1956 Lincolns/Mercurys using the original synchronous motor.  Here's a short video that proves it:

  • Lincoln Mark II

If your vehicle has a 6 volt electrical system, or a 12 volt positive ground, a Voltage Booster is required to provide the correct 12 volts, negative ground for the stereo.  HPC Power Booster:  $100.

PREWAR RADIOS:  Most $450* (Remember, if the car is still 6 volts we need to add the voltage booster, adding $100 to the price.)  Radio must be in good physical condition -- no broken interconnecting wires or cables.  Luxury-car radios with motorized tuning or other fancy gadgetry will be more -- please call for price.

* As these particular model radios involve more labor and certain parts may be hard to obtain, we cannot estimate a turnaround on these sets.  We ask that you be patient!


BT-1 Bluetooth Adapter:  Provides wireless connection from your smart phone.  Includes microphone for hands-free phone conversation.  $180

USB-1 USB/MP3 Adapter:  Play music/talking books/podcasts directly from your flash drive.  $100

BTU-1 Bluetooth/USB With Voice Command:  Provides Bluetooth and USB in one module with new features.  $230

Additional costs:  We try not to surprise anyone with additional costs, but there are a couple that cannot be avoided.  Florida sales are subject to 7% sales tax.  Return shipping is flat $20 for 48 states.  Please follow instructions for packing -- shipping damage may incur additional costs; this is preventable by following instructions.
