Most homeowners prefer a single DIN head unit for their cars. However, if they decide to upgrade to the better entertainment system, then they install the double-din unit. The standard car stereo or single-DIN unit is smaller. It comes equipped with only limited features. Double DIN, on the other hand, has advanced features that give you the best driving and entertainment experience. The bigger the display of the unit, the easier it is to control all the functions. Moreover, it is easy for the driver to access the touchscreen and adjust the features according to their requirements.
