Electric vehicles have been around for a long time, but are rapidly evolving in the automotive industry. Find out how the upcoming and inevitable transition to electrification will affect you. Whether you’re looking to build your own home theater or just want to learn more about TVs, monitors, projectors and more, we’ve got you covered. Deciding whether or not to upgrade your old factory car stereo is usually straightforward. However, factors such as a custom head unit and steering wheel controls can complicate matters. In the case of steering wheel audio controls, the problem is that the factory controls won’t work with a new head unit, and aftermarket solutions are clunky at best. Concerns about losing control of the steering wheel when upgrading your car stereo are largely unfounded, but the upgrade is more complex than most. While it’s possible to implement aftermarket steering wheel audio controls using your original equipment manufacturer (OEM) equipment, it doesn’t look like any new head unit you buy will work with your steering wheel controls. In addition to purchasing a compatible head unit, a typical installation scenario involves purchasing and installing the appropriate type of steering wheel audio control adapter to facilitate communication between the factory controls and the aftermarket head unit. If this sounds complicated, it is not. There is more interoperability than you might think: many manufacturers use the same set of compatible communication protocols, so you only need to consider a few options, not dozens. When it comes to upgrading a factory car radio, the first thing most people wonder is if it’s possible to keep the audio controls on the steering wheel. After that, it’s natural to wonder if it’s possible to keep these controls without an adapter. This topic is a bit tricky, but the basic answer is no, you can’t connect steering wheel audio controls to a secondary radio without an adapter. There are some exceptions, so it’s important to know what type of control your car has and whether you can find a working plug-and-play radio. However, in most cases an adapter is required. The main caveat is that although you do need an adapter, you can create one if you have the right level of knowledge and experience. The problem is that this is not a do-it-yourself project that anyone can handle. If you can’t design and implement an adapter unaided, it’s best to buy one. As with many other aspects of upgrading your car stereo, you need to have a plan. In the case of steering wheel audio controls, planning ahead is important because there are several moving parts that need to be properly put together. The first step in this process is to research the various adapters on the market and determine which one is right for your vehicle. Each vehicle complies with a specific communication protocol, so it is very important to find an adapter kit that works with that protocol. Then check for different hosts that are compatible with the adapter. While this narrows down your options somewhat, you still have plenty to choose from. It is also important to note that the adapter and host must be installed at the same time to save man hours. The problem here is that if you install a new head unit without even considering the controls on the steering wheel, and choose a head unit that supports this feature, you will have to take it all apart again to install the adapter. Most systems use two basic types of steering wheel input (SWI): SWI-JS and SWI-JACK. While Jensen and Sony mainframes use SWI-JS, and JVC, Alpine, Clarion, and Kenwood use SWI-JACK, many other manufacturers use either of these two common standards. The key to getting your stock steering wheel audio controls to match your aftermarket head unit is choosing a head unit with the right type of control input, finding the right adapters, and connecting them all together to make everything work together. Head unit installation is a relatively simple task that most people can complete in half a day or less, depending on the vehicle. In most cases, this upgrade is a plug-and-play operation, especially if you can find a harness adapter. Installing a steering wheel audio control is something that most home DIYers can do at home, but it’s a bit tricky. Unlike other car audio components, these devices are not designed to be plug-and-play. There are usually car specific installers and you usually have to dock with some factory wiring. In some cases, you will also have to program each button on the steering wheel to match a specific head unit function. This allows for a lot of freedom in customization, but it’s an additional complication that you need to be aware of before diving into it. If you are not comfortable connecting and programming the adapter, a car audio store can help you. Which car stereo with different prices will have better effect? Two car enthusiasts replaced the head unit in the same Subaru – but one used an expensive replacement, and the other used a less expensive one. While neither was ultimately the best fit, the difference between a $1,600 stereo and a $49 stereo surprised them both. The audio modification was one of the many modifications James Pumphrey and Nolan Sykes made to their Subaru WRX sedan. In a new video from Donut Media, a couple put a cheap stereo into one of their cars, and the results were terrible. “He doesn’t have [Apple] Carplay. The sound quality here is noticeably worse than on standard consoles.” These two car junkies are getting hundreds of dollars for precise modifications to their cars, but car modifications don’t have to cost a fortune.

What is the significance of car radio?
Like equipment that looks tall but doesn't need to be cleaned, such as skylights and headlights, the use of car navigation feels very bad. Not only do some car navigation screens have poor UI design, but the reaction sensitivity resembling a resistive screen is now driving people crazy. So why are car companies still very enthusiastic about using car navigation with such poor touch? The primary role of in car navigation is to assist drivers in identifying road traffic. However, with the rapid development of mobile phones, the usage rate of car phones is far less than that of mobile phones. Looking at the sales of mobile phone holders online, it can be verified that customers often rely more on mobile phones than car phones. For example, when I open a certain navigation when getting on the car, the map of the in car interconnected system is not only slow to update but also messy to operate, resulting in poor user experience. For this point, some car companies can say that they have a very thorough understanding of customers' thoughts, considering mobile phone holders for customers at the original factory. Although low-end models are not equipped with car navigation, they are equipped with "humanized" mobile phone holders for customers. This difference in product concavity and concavity is not excessive, after all, car machines are not produced by car companies, and purchased car machines have cost control. So the primary reason why car companies are still enthusiastic about such a weak car engine is that it can become additional capital to enhance the selling point of the product, and then achieve higher prices and profits. Car mechanics has now become one of the fields of research and expansion for car companies. How to make car mechanics more user-friendly, intelligent, and networked, and use car mechanics to assist in driving, has become one of the current development directions. For example, Windlink in Spring Breeze and Zebra Zhixing in SAIC are all research achievements in this field. In the future, car mechanics will not only be used for navigation, but also be more networked and intelligent. In addition to assisting in driving and improving product profitability, another important role of car mechanics is to "look at the atmosphere". In this society where I have you or not, car mechanics have become one of the goals for customers to compare with each other. Just like the small blackboard work of the KX7 back then, when others are equipped with larger and more technological central control screens, while the KX7 uses such a cheap small blackboard, it inevitably depreciates the price In fact, car navigation is quite challenging now, and its ease of use is far less convenient than that of a mobile phone. However, in the future, it will not only be a car navigation, but also an intelligent assistant that can assist drivers in completing more tasks. In this context, car navigation can also improve the visual perception of the interior, and can also increase the profitability and price of the entire vehicle to another level.

Introduction to Car Radio
1. The chip of the satellite signal receiving module. This is an important component that determines the accuracy and speed of GPS. Choosing a outdated chip means that when your car reaches an intersection, you need to wait for GPS to tell you how to go before you can drive. If you walk at normal speed, you will occasionally have to return to the original route and correct errors. Currently, the first to third generation chips on the market are in use, and most dealers do not tell you the chip performance of their products when selling GPS. It's like when you buy a phone, people won't tell you how much CPU the phone has, because once they tell you that the CPU version of the phone is very low, it will affect its usage speed. Would you still buy this phone? (I use a certain brand of GPS navigator, and at every intersection from Shenzhen to Zhuhai, the GPS response speed and driving speed will differ by a few seconds to more than ten seconds, making the driving experience very uncomfortable.) 2. The speed of map updates. Nowadays, the speed of construction and development in various places is very fast. If manufacturers do not provide map update services in a timely manner, your GPS will not have much use. Of course, GPS sales personnel will not proactively tell you about this. The salesperson will tell you how many places and towns can be covered by the maps installed in its GPS. But if you think about it, if the map is not updated, it won't be long before your GPS displays a map that is very different from the actual one. (I used another brand of GPS navigator to travel 160 kilometers from Fuxin City to Changchun City. The reason is that the Tiechao Expressway has been open for 10 months and there is only 380 kilometers between the two places. However, the GPS navigator still instructed me to take the old road of Shenha Expressway, which is 540 kilometers between the two places.) 3. Provide a time for free updates. Generally, GPS produced by informal enterprises uses cracked maps and does not provide update services. Some companies still use genuine maps but do not provide update services. Some companies also use genuine maps, but there is an additional fee for map updates. Some companies also provide you with long-term free map updates. You should know that the price ratio of the common GPS navigator hardware itself in the market to the price of genuine map software is about 1:3 or 1:6, which means that the hardware is cheaper than the software. So, when choosing a GPS navigator, you need to look at both hardware and software. Otherwise, the GPS you have in hand is a useless piece of junk.

How to use the car radio
Introduction to Car Radio - Principles GPS is composed of three major components: space satellites, ground monitoring, and user reception. In space, there are 24 satellites forming a distribution network, each located in 6 Earth's quasi synchronous orbits with a tilt angle of 55 ° and a distance of 20000 kilometers from the ground. There are 4 satellites in each orbit. GPS satellites orbit the Earth every 12 hours, enabling any location on the Earth to simultaneously receive signals from 7-9 satellites. There is a total of 1 main control station and 5 monitoring stations on the ground responsible for monitoring, telemetry, tracking, and control of satellites. They are responsible for observing each satellite and providing observation data to the main control station. After receiving the data, the main control station calculates the accurate position of each satellite at each moment and transmits it to the satellite through three injection stations. The satellite then transmits this data to the ground through radio waves to the user's receiving device. Only after more than 20 years of research and experiments on the GPS system and a cost of 30 billion US dollars, the 24 GPS satellite constellation with a world coverage rate of 98% were officially deployed in March 1994. Now the application of GPS system is not limited to the military field, but has developed into various fields such as vehicle navigation, atmospheric observation, geographical survey, ocean rescue, manned spacecraft protection and detection. Introduction to Automotive Navigator - Composition The operation of the GPS navigator also requires a car navigation system. Having a GPS system alone is not enough. It can only receive data sent by GPS satellites, calculate users' three-dimensional position, direction, and motion speed and time information, and has no path calculation ability. In order for the GPS receiving device in the user's hands to achieve route navigation function, a complete car navigation system including hardware devices, electronic maps, and navigation software is also needed. The hardware of the GPS navigator includes components such as chips, antennas, processors, memory, screens, buttons, speakers, etc. However, as of now, there is not much difference in hardware between GPS car navigators in the market, and it is difficult to distinguish who is good from who is bad with built-in software maps. Currently, there are eight mapping companies in China engaged in the surveying and development of navigation map software, such as 4D Tuxin, Kailide, Daodao Tong, Chengjitong, After several years of continuous development and improvement, we have been able to provide quite good navigation map software. To summarize, a complete GPS car navigator consists of nine main components: a chip, antenna, processor, memory, display screen, speakers, buttons, expansion function slots, and map navigation software.
