Modern car radios can do a lot: They communicate with your smartphone, show you the way and connect to the rear view camera, whose image they show on large displays .
Navigation in car radios in double-DIN format is done via built-in GPS technology or alternatively via apps such as Google Maps. The maps are displayed on touchscreen monitors measuring up to ten inches diagonally. Navigation instructions are shown in the vehicle's cockpit display in addition to the device screen, and navigation functions can be controlled using steering wheel buttons. In some cases, there are connection options for the rear view camera or pedestrian detection. Seat heating or air conditioning can also be controlled.
To ensure that as many of the functions mentioned above are not only possible with the factory-installed entertainment solutions, the manufacturers of aftermarket devices also equip their models with as many connections as possible. Access to the cell phone is via Bluetooth, USB or Lightning. There are also numerous connections on the back of the car radio: for rear cameras that help when reversing, microphones for hands-free calling, GPS antennas, additional amplifiers, the steering wheel remote control.
Advantages and Disadvantages of Car Radios
Functional diversity requires double installation space
The full range of functions of the radio requires a certain size. Therefore, the device slot in the dashboard must be large enough. In the past, a single DIN slot (dimensions 180 millimeters x 50 millimeters) was sufficient, but today the double DIN slot (dimensions 180 millimeters x 100 millimeters) is standard - especially for retrofitted devices with large monitors.
