After you have made sure that your car can accommodate a particular type of DIN unit, you can start looking for units offering different features and additional functionalities. There are many functions to choose from, and each has its pros and cons. Here is a small glossary of the various elements you might want your DIN unit to have. Touchscreen Display While a touchscreen display looks better and provides a crisp feedback response, it does not always have the best functionality. So look for a touchscreen display that comes along with a few physical controls in order to control your unit’s features easily and based on muscle memory. Bluetooth This is one of the best wireless fidelity options in the market. It is supported by nearly every device out, be it smartphones, tablets or laptops. This allows for a secure wireless connection with your unit without worrying about the hassle of wires. A Bluetooth enabled head unit is always the better choice for calling-related features, navigation, and other hands-free functionalities. Support For Music Streaming Apps No one can resist listening to some good music while on a long drive or when stuck in traffic. So, it is imperative to look for a stereo unit that can play as many types of music as possible while offering as many capabilities as possible. A good connection to any streaming platform makes a stereo unit better than ones that don’t offer this feature. Granted that these would cost more than conventional stereo units, but the added functionality and versatility in playing music more than makes up for it. Smartphone Integration With Apple CarPlay & Android Auto This is the leading cause of looking for newer and advanced stereo options. Many higher-ended options include software to seamlessly integrate your android or apple phone with the stereo unit to get the complete integration experience. This way, you can use maps, Siri, or even Cortana while driving, without having to use your hands or going through the hassle of setting up accessories. In-Dash GPS Navigation This feature is adored by many. People who travel would like to look for an infotainment system that comes with a built-in GPS and satellite radio. This allows for better navigation. Granted that a mobile phone can perform the same functions, but it is always better to have a stationary and built-in mapping device that can display your routes and play music simultaneously, without needing any inputs from you. DVD Playback & Rear Seat Entertainment Support This function is useful for newcomers who want to have something advanced in their cars but still retain some of the old functions. It also lends a rugged look to your car’s aesthetics. Moreover, many units allow integration with OEM rear seats. This way, everyone can enjoy and use the infotainment system (like sharing movies or listening to songs with the family) to its fullest. Backup Camera Support No amount of caution and practice can take away your fear of backing up a car without direct audio or visual cues. The integration of the infotainment system with the rear camera allows you to see your vehicle’s rear better than a standard screen. This saves you the hassle of looking back all the time and provides a good safety option to look at your car’s rear all the while sitting safely in the confines of your car. So, go through the unit’s specifications carefully, as the absence of this functionality can be a substantial loss. Support For Satellite Radio Satellite radio, such as SiriusXM, has been a long time favorite of many audio enthusiasts. It is a staple for many who are looking to expand their musical palate. Therefore, having a system with satellite radio compatibility offers many benefits, both in its versatility and functionality. USB & AUX Inputs Since the late 2000s, all OEM units come with AUX and USB inputs. The tradition still continues, with many aftermarket units offering these inputs facilities to increase playback options and versatility. Audio CD Playback The CD playback option is targeted at people who have a collection of music CDs that they would not want to part with. Though it is not very versatile, it can be a good option for people looking for something advanced, while retaining a hint of nostalgia. Support For Digital Media Files Like MP3 MP3 is one of the most widely used file formats, so it is no wonder that nearly every aftermarket unit supports this audio format. Many older OEMs did not include this support, so upgrading to a system that does only increases your repository of music and playback options. Equalization & Time Correction This is one of the more advanced options and allows the user to tweak and modify specific channels according to their taste. Time correction is the cherry on top that cuts down on echo and time delay, providing crisp and clear music playback. Support For High-Resolution File Formats Such As FLAC Finally, file formats such as FLAC are the music streaming industry’s pinnacle of musical purity. Therefore, it is no wonder that any unit that supports this feature will pull ahead of its competitors in terms of clarity and reliability.
