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.
  • AM/FM Stereo.  Tuning knob, buttons, seek bars, etc., operate as original but performance is digital.
  • Cutting-edge Class S audio amp is cool and efficient, provides up to 180 watts (45x4).*
  • Switchable Loudness contour improves fidelity at low volume levels.
  • AM/FM switching, balance/fader, other adjustments are performed easily with front panel controls.**
  • Rear-mounted Audio Input jack lets you play accessories through stereo.
  • Stereo is fully protected from extreme cold/heat, voltage transients, and improper wiring.
  • Warranted for one year -- although PCB failures are virtually nonexistent.
*If vehicle is 6 volts and/or positive ground, total available power is less.
**Varies depending on model.  Example, if radio has AM/FM switch, it will operate as original.  Otherwise this is performed by powering off and on.  There are other considerations for tone switch, fader, etc.
BEWARE OF INFERIOR PRODUCTS!  There are other conversions, as well as high-priced "repro" looking radios, that are NOT up to Aurora standards.  Don't make an expensive mistake!
  • Bluetooth:  Fully integrated with the FMR Stereo, FCC Certified, supports the new 4.1 format.  Includes Voice Command for easy operation.
  • USB:  Allows playback of MP3, AAC, Ogg Vorbis from flash drive.  Can also charge cell phone.
  • BTU-2 Option includes Bluetooth AND USB, at reduced price.
  • Line Outs for adding external amps.  Jacks include front left/right, rear left/right, and mono subwoofer.
  • Auto volume for 1957 Thunderbird.  Works with car's original distributor hardware.
Note:  Recently several customers have asked about using our 3.5mm stereo jacks with accessories/amps that have RCA jacks.  This is a non-issue!  Patch cables are readily available at electronics stores, as well as big stores such as Wal-Mart and Target.  We use 3.5mm jacks for several reasons.  For starters, the BT and BTU options incorporate them on the PCB's.  Another reason, a conversion which includes Line Outs and a BTU-2 would require TWELVE RCA jacks, and many sets simply have no place to put them!  Most devices today use these 3.5mm jacks.
I found this, and several others like it, on Wal-Mart's website.  SKU #TRIPP-LITE P314-006.   I believe their price is about $3.
If you have RCA cables already installed, use an adapter such as this one.  Again, Wal-Mart SKU #SA-iEM2TPSF.

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.
