Finally — Bluetooth in the Car You Already Own

No aux jack. No Bluetooth. If your car was built before 2014, chances are your radio is locked in the past — while your music, podcasts, and phone calls sit trapped on your phone. The DashTune Bluetooth FM transmitter fixes that in about sixty seconds, without tools, installation, or a $700 stereo swap.

Plug it into your cigarette lighter socket, match your radio to the number on its display, and your phone streams straight through the speakers your car has had all along.

Stream Music Through Your Factory Radio — Without the Static

Older FM transmitters earned a bad reputation, and DashTune exists to end it. It receives a clean digital Bluetooth stream from your phone, then digital PLL tuning locks it onto one empty FM frequency and holds it there — no drift, no crackle, no fiddling. Powered by your car's 12V socket, it broadcasts at the full legal limit on every drive. Your radio can't tell the difference between DashTune and a real station. That's the point.

Take Hands-Free Calls Legally in Any State

Handheld phone use behind the wheel is now banned in 33 states — and older cars got left out of the hands-free era. DashTune turns your car stereo into a speakerphone: the noise-reduction mic picks up your voice, callers come through every speaker, and your music auto-mutes for calls and resumes when you hang up. One button, both hands on the wheel.

Fast-Charge Two Phones While You Drive

Dual USB ports (including QC fast charge) plus USB-C mean your phone — and your passenger's — arrive full. The digital display shows your frequency at a glance, the control knob adjusts volume and tracks, and the soft LED ring makes it easy to find at night.

Works With Any Car, Any Phone

  • Any vehicle with an FM radio and a 12V socket — 1990s to today
  • iPhone and Android, no app required
  • Auto-reconnects every time you start the car
  • Setup in 60 seconds: plug in, set frequency, drive

Try It Risk-Free

If you can't get clear sound in your car, you don't pay — every DashTune is covered by our 30-day money-back guarantee. Your paid-off car is one plug away from feeling new again.
