FMR-1 Stereo

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're keeping the prices as simple as we can, but not all radios are the same -- some take extra time and hardware.  Prices are based on cost and difficulty.  NOTE:  ALL prices are for 12 volt, negative ground electrical systems.  If your 6 volt car has been converted, these prices apply.  if the vehicle still uses 6 volts and/or positive ground, a voltage booster must be added which adds $100 to the price.

PUSHBUTTON RADIOS:  The vast majority of vehicles from 1950 through about 1980 had a radio with two knobs and five pushbuttons (more or less).  Some were manual-tune only.  For these sets, the following prices apply:

Prewar sets:  PLEASE CALL.  Many sets are in the $400-450 range, however we are not accepting multi-piece sets with automatic tuning features.
