Now picture this:

  You’re driving down the road in your cherished classic or hot rod. You reach over and with a simple twist of a knob on your original radio, you tell it to phone your house. The call comes in over the radio and when finished, it announces that the call is terminated and returns you to your music. You then get nostalgic for that certain song you haven’t heard in a while, so you twist the control again and tell the radio to start playing that song. For a minute you actually forget that you aren’t in your modern car but in your classic car. Sound like science fiction? Not with the new BTU Smart-3.2 with Voice Command and Voice Assist from Aurora Design.

  While some companies call off-the-shelf adapters or clunky boxes “solutions”, Aurora Design is the only company to offer a custom designed, fully integrated, full featured, Bluetooth/USB/AAC/MP3/Ogg/FLAC solution that truly brings your radio into the 21st century. Because the BTU Smart-3.2 was designed to fully and seamlessly interface to the FMR-3.0 receiver, no aftermarket add-on product is even in the same league. No cords to fumble with, no hard to reach little buttons, no touch screens, no fiddling with the radio to get into the right mode, the FMR-3.0/BTU Smart-3.2 combination is fully automatic just like a modern car. Using only your original radio controls, you can have a truly modern solution that rivals any new car!

  Streaming audio from a USB FLASH Drive or from your Bluetooth device is easily controlled with just a twist of a knob. Start and stop playback and skip forward and backwards through your songs. Answer and place phone calls just as easily. With literally thousands of songs at your fingertips, you’ll never run out things to listen to on that cross country tour! And so you don’t get lost, let your Bluetooth device that supports turn by turn navigation direct you to your destination through your radio.

  And now with the introduction of high quality AAC support, all your music will sound even better! No need for your phone to convert your music to low quality SBC, or for you to spend time converting your music library to MP3 format, the BTU-3.2 will playback AAC encoded music directly for the highest quality, most convenient operation possible!

  The groundbreaking new Voice Assist feature joins the Aurora Design innovated Voice Command feature. Just as the Voice Command feature lets you speak to your radio, the Voice Assist feature lets your radio speak to you to help you with basic radio operation. No having to remember confusing beep tones or complicated LED flash patterns and colors. The radio will announce “ready to pair” when you open Bluetooth pairing. It will then tell you “pairing completed” or “pairing not completed” so you’ll know exactly what’s going on.

  The microphone on the BTU Smart-3.2 can be mounted internally to your radio, or externally for best audio quality. Even if your radio has an internal microphone, you can still plug an external microphone in at a later date to get even better quality! The BTU-3.2 contains advanced echo cancellation and noise reduction algorithms for the best sound possible. The external microphone comes with a 9.8’ (3m) cord so it can be place anywhere in the vehicle for the best performance. Notice on most modern cars with hands-free operation, the microphone is mounted on the headliner right behind the windshield. With the BTU Smart-3.2’s external microphone this can also be easily accomplished.

  No other product can boast the easy of use, performance and features of the BTU Smart-3.2. For the ultimate in 21st century performance in your classic radio, look no further than the

FMR-3.0/BTU Smart-3.2 combination.
