Single DIN vs Double DIN Head Units

The head unit is your system's brain, and the upgrade you touch every single day.

What "DIN" means

DIN is the chassis size. Single DIN = 2" tall (classic radio slot). Double DIN = 4" tall, which is what makes big touchscreens possible. Your dash opening decides, most vehicles from the mid-2000s on accept double DIN with the right dash kit.

Why upgrade at all?

  • Apple CarPlay / Android Auto, maps, music, calls, and messages with your voice. Once you have it, you never go back. Browse CarPlay / Android Auto units.
  • Better sound, higher-voltage preouts, real EQ, time alignment, and clean signal for amps.
  • Camera ready, add a backup camera even on older vehicles.

Mech-less (Digital Media) receivers

No CD mechanism = shallower chassis, easier install, lower price. If you stream everything, a digital media receiver is the smart buy.

What you'll need for install

A dash kit for a factory look, a wiring harness so you never cut factory wires, and sometimes a steering-wheel-control interface. Tell us your year/make/model and we'll list exactly what your car needs.
