What is a Double DIN Head Unit?

Double DIN head units are car stereo systems that measure 4 inches in height and 7 inches in width. This is twice as tall as a standard Single DIN unit, which is only 2 inches high. DIN refers to the standardised sizing for car stereo units, originally set by the German standards organisation, Deutsches Institut für Normung.

Benefits of Upgrading to a Double DIN Head Unit

• Larger Display – A bigger touchscreen makes it easy to see everything at a glance – no more squinting or distractions.
• Smartphone Integration – Apple CarPlay, Android Auto, and Bluetooth let you take calls, stream music, and use apps hands-free.
• Enhanced Sound Quality – Enjoy richer audio with custom settings, built-in amplifiers, and advanced sound processing.
• Built-in Navigation – Many models have GPS, so you don’t need to rely on your phone for directions.
