FMR-1 Stereo

The Aurora Design FMR Stereo Conversion has been revolutionary.  Your radio receives AM/FM Stereo, with performance and features not found in most aftermarket stereos!  Why chop your dash for something less?

Your original radio is disassembled, cleaned and detailed, then reassembled with modern components replacing the outdated tubes and condensers.  In the dash the radio looks and feels original -- but has performance comparable to modern stereos found in new cars.  It SHOULD -- after all, it is built to SAE specs using many of the same components!

Is the stereo compatible with your original antenna?  YES, in fact there are no more trimmer adjustments -- it's automatic.  Speakers?  You'll definitely want to upgrade, as the FMR Conversion offers up to 45 watts per speaker, full fidelity, while original speakers typically ware designed for 3 watts midrange.  We can help with speaker replacements.

Operation:  for the most part it is unchanged.  However if the radio is originally AM, band switching is performed by turning the radio off, then immediately back on.  Balance, fader, loudness on/off, and other features can be performed using existing controls.  If the radio has an original balance, fader, AM/FM switch, etc., these will be utilized.

A note about LED indicators:  Older conversions used LED indicators to display status.  Although Aurora can use these, they are unnecessary and we do not install them -- for the sake of keeping the appearance totally original.
OPTIONS:  Bluetooth, USB, Line Outs, and other options are available.  Scroll down or click here for details!

All prices are for cars with 12 volts, negative ground, including 6 volt vehicles which have been converted to 12 volts.  If your vehicle is still 6 volts, and/or positive ground, an HPC Power Booster is required.  Scroll down or click here.

USA Radios:

US-made radios fall into 5 categories.  The prices are simple enough, but there are a few exceptions thanks to some pretty bizarre designs out there.

All-Transistor AM radio, pushbutton or manual-tune:  $385

(Some 1961-62 sets, nearly everything made 1963 and later.  Mopar sets with thumbwheels -- yes we do them!)

AM/FM pushbutton sets (Stereo or Mono):  $400

Tube or hybrid sets, 1946 and later, pushbutton, Roto-Matic, or manual-tune (Except Cadillac/Lincoln as below):  $400

1946-47 Cadillac, 1946-48 Lincoln, qualifying prewar sets$450

(Prewar sets, particularly 2-3 piece types with interconnecting cables, must be in good physical condition to qualify.  Fancy sets with elaborate gadgetry may be higher, or may not qualify.  Prewar/40's Cadillac/Lincolns are considered projects, so expect turnaround to take longer.  Best to contact us first.)

Signal-Seeker sets:  Trademarks for these include Wonderbar, Town & Country, Electro-Touch, Travel-Tune, and others.  These sets, made 1950 and later, have either motorized or springwound tuning mechanisms.  Pressing a bar or button causes the tuner to move back and forth to find stations.  Pricing is complicated, as some models require extra work or hardware.

  • Wonderbar radios, GM and Studebaker/Packard, 1950-1957, also 1958 Buick and Cadillac:  $495

  • Wonderbar radios, 1959 and later Buick, Cadillac, 1958 and later all others:  $445

  • Cadillac 1957 Eldorado all-transistor:  $445

  • Town & Country, 1956-59 Ford, 1958-59 Edsel, 1956-57 Thunderbird, 1957 and later Mercury:  $445

  • Town & Country, 1956 Lincoln & Mercury, 1956-57 Continental Mark II:  $545

  • Town & Country, Lincoln 1957 and later:  $495

  • Mopar Electro-Touch, 1955-56:  $495

  • Mopar signal seeker 1957 and later:  $445

Foreign Cars & Trucks (1946 and later):

Many European imports, such as VW, Triumph, Volvo, and Alfa-Romeo have American radios.  Prices above apply.

Many Japanese vehicles such as Datsun and Toyota have basic radios similar to American, and the above prices apply

European radios including Blaupunkt, Becker, Radiomobile, and Pye, pushbutton or manual-tune:  $420

European Signal seeker sets (such as Jaguar E-Type):  $495

(I bring up the E-Type specifically, as this radio looks like a basic pushbutton set.  However you enable seek by pressing the tuner knob, and sensitivity is selected by the knob behind it.)

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, for other places contact us for estimate.  Please follow instructions for packing -- shipping damage may incur additional costs; this is preventable by following instructions.

Standard Features:

These features come STANDARD with every FMR Stereo Conversion:

  • AM/FM Stereo with digital tuning performance, using radio's original analog dial

  • LINE IN Audio Input jack, for playing accessories through the stereo

  • Supports up to 4 speakers.  Radio automatically adjusts for speaker arrangement; if only 1 speaker it goes to mono

  • Protection against shorts, reverse voltage, excess climate, or other abuses that would destroy other car stereos

  • Class S audio amp runs cool and efficient

  • Loudness contour (switchable) boosts bass and treble at low levels

  • PCB interface designed to be gentle on antique, fragile switches and controls

  • One year warranty -- even though the track record of these PCB's is SUPER!


Aurora Design BT-2  BT-2 Bluetooth Adapter:  This is a FULLY CERTIFIED, professional Bluetooth 4.1 device.  You can stream music from your smart phone or similar device, make hands-free phone calls, and even use your phone's features (such as SIRI) to navigate, get weather reports, and answer questions.  It even supports call waiting and conference calling!  Voice Command and Voice Assist make it easy to use!  Includes an external microphone (and internal microphone on certain radios).  $170

NOTE ABOUT MICROPHONES:  EVERY Bluetooth-equipped conversion includes an external microphone for hands-free calls and Voice Command.  SOME sets also include an internal microphone as well -- inside the radio itself.  The internal microphone is totally invisible, and makes installation easier, but cannot be installed on some models.  If the radio has a built-in speaker, it will not work properly.  Most manual-tune radios or European sets are made such that it is physically impossible.  Regardless, an external microphone is always included as it is generally the better performer.

How well does this perform?  Good question:  we know that hands-free calling sounds great in a new air-conditioned Cadillac, but how does it sound in a street rod?  We tried this out in our 1964 Thunderbird -- with Edelbrock intake, cherry bombs, windows rolled down, driving in traffic.  Actually, it's pretty impressive -- clear, with good noise cancellation.  We'll try and post some recordings soon.

Aurora Design USB-2  USB-2 USB/MP3 Adapter:  Play MP3 music, podcasts, and other recordings from any flash drive directly into your stereo!  Supports newer formats including AAC and Ogg Vorbis.  Radio will have a USB dongle on the back; use an extension of your desired length to bring it to the glove compartment or wherever it's convenient.  Can also be used to charge a cell phone battery. $100

Aurora Design BTU-2BTU-2 Bluetooth/USB:  This provides Bluetooth 4.1 AND USB, for a lower price!  Includes a flash drive with quick start instructions -- get your library started right away!  $220

Line Outputs:  Offers four post-fader line outputs for external amp and one mono subwoofer line output.  $15

Automatic Volume Control:  Intended for 1957 Thunderbirds, this option replicates the function on the original radio, where the volume changes with the motor RPM.  For 1957 Thunderbird, $20For other sets, contact us.

Tube Emulation Mode:  Car radios made before about 1962 used indirect-heated tubes.  Like most other tube-type radios and TV sets, the radios took about 10-15 seconds to "warm up" as it slowly began playing.  If you want to impress the concours judge, or just want that vintage feel, your FMR Stereo can be configured to warm up softly in the same manner!  $20

VOX Input mode:  Input mode is normally selected by moving the tuning dial to the low end.  This works extremely well.  However if desired, Input can be selected automatically by VOX -- when an accessory begins playing, the radio will switch by itself.  If no sound is heard for 20 seconds, the FMR switches back to radio.  Certain radios, such as 1950's Cadillacs with no tuning knob, will have VOX selected as default.  NO CHARGE for this feature; just let us know if you want this.

FMR-CM-1:  Here's an interesting new option, just released!  Many modern vehicles have a feature where the radio continues playing when the ignition key is shut off.  It will shut down when the door is opened, or after several minutes.  This feature is now available on the FMR-2!  This works on 6 or 12 volts, but requires negative ground.  This is currently a special order option, so please allow more time$75

HPC Power Booster:  Required for 6 or 8 volt vehicles, or positive ground.  Converts power to 12 volts negative ground, to power stereo.  $100.
