FM and Bluetooth Conversions

Powered by Aurora Design

The Aurora FMR 2.7, as seen on MotorWeek as well as in Hagerty Magazine, completely replaces all of the factory AM or AM/FM tube or solid state electronics in the radio, and interfaces directly with your original tuner and volume/tone/fader and/or balance controls. Even stock stereo indicator lamps and mechanical automatic signal seeking mechanisms can be incorporated just as seamlessly with the Aurora. This is the restorer’s choice for incorporating modern features and reliability discreetly into classic car or truck factory radios. Even Concours level judges are apt to be fooled by the Aurora’s Tube Emulation Mode, which simulates a tube radio’s original warm-up time; in such installations the original mechanical vibrator can remain powered for an authentic sound effect, while remaining otherwise nonfunctional.

Aurora Electronics are designed AND manufactured in the USA.

Conversions incorporate the following features and are tailored to meet your needs:

Bluetooth Streaming Audio
Bluetooth hands-free phone
Voice Command/Voice Assist
USB AAC/MP3/Ogg/FLAC Playback
USB 2.1A Universal Charger
AM/FM 180W 4 Channel
HD Radio Reception
Automotive OEM Quality

Conversions incorporating the Basic Bluetooth (Bluetooth Only) or Bluetooth Plus (Bluetooth with USB) level tiers allow your wireless music device (iPhone/iPod, Mobile Phone or MP3 Player) to be controlled through the radio’s own knobs. This means you can scan through your music library as if you are tuning the radio. Hands free calling via discreet built-in mic standard on most Bluetooth conversions, and an optional clip-on visor mic is included standard in case the built-in proves unsuitable for your vehicle.

Other optional accessories include the new HD Digital Radio Tuner which will allow your converted radio to pick up stations broadcasting in HD, and the Courtesy Module, which allows your radio to remain powered on until the door is opened- same as a modern factory car stereo, even after the ignition is powered off. The Courtesy Module also has a built in battery voltage sentry which will automatically power the radio off if your car’s battery voltage begins to drop.

Basic AM/FM/Aux conversions start at just $395. Additional options such as Bluetooth and USB functionality are available at additional cost. We take a $100 deposit to get started on any Basic conversion, and a $250 deposit to get started on either Bluetooth-tier conversion. Sorry, we do not ship internationally. Radios which are excessively dirty will incur an additional cleaning charge. Otherwise, all prices include basic touch up of dial face, lens, fresh paint on the dial pointer, and a new dial lamp.

The Process: When you send in your radio we’ll first give it a preliminary to make sure it’s suitable for conversion. While we don’t reuse the original receiver, power supply, or amplifier electronics inside your radio, components such as the original mechanical tuner, volume, tone, fader/balance, and/or band switches are reused and integrated in with the new Aurora Design electronics. These must all be in usable or rebuildable condition, though if any of these original components is in need of replacement or repair, then this is does incur an additional charge.

Once we determine that your radio is okay to convert, we’ll begin the process of dismantling, separating the old electronics from the chassis, and ultrasonically cleaning the case and tuning mechanism. Dial face and pointer touch up work is done at this time. Your radio is then reassembled and updated with the Aurora electronics to your specification.

Once the conversion is completed, it undergoes a burn-in test to check all of the features and functions, and to test reliability.

Power output on all conversions is 45Wx4 with a 4 ohm load.

Turnaround: 10-14 days on most radios. Heavily optioned radios may require additional time.

Note: We do NOT service customers outside the US.
