What's The Din Difference?!

A comparison of a single Din vs. double Din unit.

By Alpha-Nav

When researching about an aftermarket gps navigation or stereo unit, odds are you're going to come across the term Single Din vs. a Double Din.  So what is a Din, and which do you choose?

Din (Deutsches Institut für Normung) which, in English, means the German Institute for Standardization, refers to a standardized radio/stereo size for vehicles (large enough to accept a CD).

The size of car stereo or GPS navigation head unit is deemed either single DIN or double DIN. DIN units measure 2" x 7", while double DIN units measure 4" x 7". Double DIN was adopted by some car manufacturers to fit larger radios and the evolution of GPS navigation units.

Which do I select for my car?

You’re probably safer with a single Din if you have an older model automobile.   Based on age of the vehicle, the dashboard was strictly built for single Din stereos.  With today's advancements in aftermarket navigation, you can still have all the same “bells and whistles” of a double Din gps unit, but it will be tucked away within the dashboard when not used.  Stay away from fitting a double Din where a single Din unit used to exist, this may cause problems with installation.

As for newer model vehicles, depending on the make and model, it will allow you to house a double Din.  Most car manufacturers will produce cars that may not come stock with a navigation unit, but will allow for you to purchase and install an aftermarket navigation system. The dashboard comes equipped with enough space along with custom made attachments to house a double Din navigation system.
