Car Radio
Mono AM Radio to Touchscreen Infotainment: Nine Decades of Automotive Head Units
Car audio has been a popular hobby and obsession since the early days of both cars and radios, and the head unit has evolved a lot throughout the years. They’ve gone from simple, monaural AM radios to complicated infotainment systems, and a number of technologies have come and gone over the intervening decades.
Most head units still include an AM tuner, but eight-track tapes, cassettes, and other technologies have faded into history. Other technologies, such as the compact disc, could also disappear over the next few years. That might seem far fetched, but the history of car radios is littered with abandoned technology that was once considered state of the art.
The First Commercial Head Units
1930s
Enthusiasts had already been finding creative ways to integrate radios into their cars for over a decade, but the first true car radios weren’t introduced until the 1930s. Motorola offered one of the first car radios, which retailed for about $130. Philco also introduced an early head unit around that time.
When inflation is taken into account, $130 translates to a price tag of about $1,800. Keep in mind that this was the era of the Model T, and you could buy an entire car for around two to three times the asking price of Motorola’s first car radio.
AM Continues to Dominate
1950s
- FM Receivers
- record players
Head units dropped in price and increased in quality over the intervening years, but they were still only capable of receiving AM broadcasts until the 1950s. That made sense because AM stations held a stranglehold on the market share at that point. That might seem strange from a modern perspective, but there was a time when FM radio wasn’t exactly a popular medium.
Blaupunkt sold the first AM/FM head unit in 1952, but it took a few decades for FM to really catch on.
The first on-demand music system also appeared in the 1950s. At that point we were still almost a decade away from eight tracks, and records were the dominant force in home audio. Record players aren’t exactly the most shock-proof media ever invented, but that didn’t stop Chrysler. Despite all common sense, Mopar introduced the very first record playing head unit in 1955.
The Car Stereo is Born
1960s
- first eight track
- first stereo
The 1960s saw the introduction of both eight-tracks tapes and car stereos to the world. Up until that point, all car radios had used a single audio channel. Some had speakers in both the front and the back that could be adjusted separately, but they still only had one audio channel.
Early “stereos” placed one channel on the front speakers and the other on the rear speakers, but systems that used the modern left and right format appeared soon after.
The eight track format actually owes a lot to car head units. If it wasn’t for car audio, the entire format probably would have floundered. Ford pushed it pretty hard, though, and all of the other OEMs eventually picked up the format in order to compete.
Compact Cassettes Arrive on the Scene
1970s
- first cassette tape head unit
The eight-track tape’s days were numbered from the start, and the format was rapidly pushed out of the marketplace by the compact cassette. The first cassette head units showed up in the 1970s, and the format was substantially longer-lived than its immediate predecessor.
The first cassette deck head units were relatively hard on tapes, and Maxell actually based an ad campaign in the early 1980s on the concept that its tapes were hardy enough to stand up to the abuse. Everyone who ever put a cassette into an in-dash tape deck remembers the sinking feeling associated with the head unit “eating” a precious tape.
The Compact Disc Fails to Dislodge the Compact Cassette
The first CD head units showed up less than 10 years after the first tape decks, but adoption of the technology was much slower. CD players wouldn’t become ubiquitous in head units until the late 1990s, and the technology coexisted with the compact cassette for more than two decades.
CD Players Become Dominant
1990s
- Video head units
- CD-RW compatible head units
CD players became increasingly popular in head units during the 1990s, and there were a few notable additions toward the tail end of the decade. Head units that were capable of reading CD-RWs and playing MP3 files became available, and DVD functionality also appeared in some high end vehicles and aftermarket head units.
Bluetooth and Infotainment Systems
2000s
- Bluetooth
- HDD-based head units
- Infotainment systems
During the first decade of the 21st century, head units gained the ability to interface with phones and other devices via Bluetooth. This technology was actually developed in 1994, but it was originally intended as a replacement for wired networks. In automotive applications, the technology allowed for hands-free calling and created a situation where a head unit could automatically mute itself during a phone conversation.
The accuracy of consumer GPS systems also increased during the first part of the decade, which led to an explosion in both OEM and aftermarket navigation systems. The first infotainment systems also started to appear, and some head units even offered built-in HDD storage.
The Death of the Cassette and What Comes Next
2010s
- The last OEM cassette deck
- Cloud-based music players
- Internet radio
2011 marked the first year that the OEMs stopped offering cassette decks in new cars. The last car to roll off the line with an OEM cassette player was a 2010 Lexus SC 430. After about 30 years of service, the format was finally retired to make way for new technologies.
According to some reports, the CD player could be the next one on the chopping block before much longer. Several OEMs stopped offering CD changers after the 2012 model year, and in-dash CD players could potentially follow suit. So what comes next?
The most obvious candidate to replace CD players are HDD-based music players, but an Internet connection removes the need for physical storage altogether. Some head units are now capable of playing music from the cloud, and others can connect to Internet services like Pandora.
Telematics History And Future Predictions
A History Of Telematics and Where It Is Heading in the Future with New Technology
Throughout the years we have witnessed a marriage of informatics and telecommunications to create telematics. We have witnessed telematics accomplish everything from improving health care quality to reducing the environmental impact of vehicles. It has revolutionized many aspects of our world, such as changing the way hospital patients are diagnosed, and lowering ordinary peoples insurance premiums.
Telematics is all about being able to get information on vehicles. Everything from fuel performance to driving speed can be tracked with telematics. The beginning of telematics could be said to have started with a tachnograph over 60 years a go. To understand Telematics you have to understand GPS, en.wikipedia.org/wiki/Global_Positioning_System
Without GPS there would not be the telematics we know today. GPS is a system that was designed for navigation and positioning. It was developed by the US defence department which knew of the importance of exact data on the positions of its assets. It was developed to fulfil the pressing need to have increased communication and exact data on the battlefield. It used the satellite network in cohesion with ground communication.
Dozens of GPS satellites now orbit the earth and enable GPS receivers to find their exact location on the planet. GPS changed from a military application to a civilian one and the US government provided free basic GPS signals to anyone in the world. It pushed for the adoption of GPS around the world and made agreements with Japan and the EU.
GPS that exists today is still under the control of the US military. It has become an indispensable tool for services all around the world. GPS basically works through a network of satellites that cross reference your signals location on the ground to the satellites location in space. By trialaterating these positions and accounting for the difference in time for the signals to be sent back and forth, you can get an exact position of your location. You use at least three satellites to determine your GPS location.
Trilateration works by calculating the relative location of different satellites by using known reference points to calculate the position of an unknown reference point.
So what exactly is the big difference between telematics and GPS? Well what telematics does is it picks up where GPS left off. It uses GPS technology to offer many different services to car owners such as navigation services. GPS just provides data about your location where as telematics analyzes and uses information along with communicating with parties outside of your vehicle. This enables a huge range of services to be offered through telematics.
The essence pieces of the telematics puzzle all converged in the 1990’s with GPS, GSM and the internet merging as one. This enabled automobiles to enter a new era of connectivity.
A lot of the development in Telematics began back in the 1984 European Parliamentary resolution to promote road safety.
Studies throughout the 1980’s kept tabs on informatics and the development of telecommunications to find new applications for road safety. Through these studies a program known as DRIVE was started to conduct research.
This community based research program focused on finding ways of using telematics for road safety, greater levels of efficiency, and reducing environmental impact.
The DRIVE program was concluded in 1992 while in 1990 another program began for telematics in general. In 1993 a European treaty was signed for telematics at the EU. The treaty enabled more research and development along with increasing telematic firms competitiveness on a global scale.
In 1993 the EU decided to increase its global competitiveness through stronger logistics networks and transportation. The digital revolution that was beginning and leaders believed that through telematics they could ride at the wave to economic success. Information and technology was seen as a key factor to being more competitive.
Telematics research was heavily promoted in the government as a way to improve traffic management and harmonizing traffic through the European Union. Pilot projects were set up to ensure the technical capability of the telematics technology to be used for this new vision.
Their vision included a more efficient Europe with safer transportation and better integration in a diverse transportation system.
Here is an overview of some key technological innovations that have occurred in telematics during the last decade:
1998 – The first hands free car gateways were introduced
2000 – The first GSM & GPS systems were brought to market
2002 – Bluetooth hand free voice gateways with advanced voice integration features
2003 – Integrated GSM phone with Bluetooth
2007 – Multimedia handset integration is introduced
2009 – Fully integrated mobile navigation using a car GSM system
2010 – 3G multimedia car entertainment system
2011 – Telematics and Infotainment systems introduced based on Linux
Where Telematics Is Headed In The Future
Several new innovations in telematics are causing exciting new advertising applications for in car entertainment that will ultimately lead to lower costs for the consumer. Navigation will become increasingly lower cost, with greater communication occurring between vehicles on the road, and a trend towards eco friendly.
Navigation systems are becoming increasingly popular as more drivers are realizing the benefits it offers, and new features are being added every year. The services available through telematic devices will separate more and more into two different categories:
Free
Premium
This is going to increase the number of options available to consumers, especially as android based telematic systems become more widely distributed.
Increased Personalization
You will be able to personalize and customize your telematic systems at an increasingly popular level. Soon you will see telematic systems merging together, with your ability to have a telematic black box and a android based entertainment system together in one unit.
Car providers are also offering more possibilities for application development. The previous model was based on manufacturers developing applications and then providing them to the user. Now car manufacturers are listening to the consumer more and focusing on following software industry leaders like Apple and Google.
Greater Interactivity
New touch based systems are more sensitive than ever and offer greater opportunities for user input. From voice control to new options like heat sensitive screens, and camera tracking of user motions. You may one day be able to control half your car by waving your finger in the air, as new technology makes it easier than ever for greater control.
Community
You will observe more community and greater connectivity between in car users, as the speeds and services of Telematics becomes proliferated. This means that you may be able to connect with other drivers on the road, social network, and even develop virtual car pooling to help save on gas.
Greater Openness
You will see the telematic systems moving from closed manufacturer software to open software with universal standards. Instead of manufacturers trying to each develop their own proprietary systems, Telematics will become increasingly standardized and cross compatible between vehicle models and manufacturers.
This will lead to more applications and services being available to Telematic customers as a whole, in addition to greater flexibility when you change car models.
Easier To Use
Ease of use ranks as the most important feature for car users, so developers are trying to make the systems increasingly user friendly for drivers. This includes better voice recognition and control technology, more features, applications designed for drivers, and a simpler interface that is more intuitive.
In a word, we can see telematics becoming more like Apple products.
More Telematic Feedback
Your telematic system will be increasingly capable of providing you with information and feedback while you are on the road. There are many new exciting developments underway such as:
> Post secondary learning from your vehicle
> EBooks being read aloud while you are driving
> Having your favorite newspapers read
> Feedback on your driving
> Feedback on road conditions
> Warnings and updates about traffic
Emphasis on Infotainment
One of the big growth areas right now and for the foreseeable future of telematics is the information entertainment models. These models are capable of providing drivers with a wide range of digital entertainment services. In the future we will see many exciting new possibilities such as:
> Pay Per View Movies
> Television subscriptions
> In car games for passengers
> Vehicle based games
> Cloud syncing with your music files
> Digitally access your computer in your office or home
For many people the road can be a boring place if you are stuck in rush hour traffic or on a long journey. Perhaps you are just waiting for someone and need to kill time. Automakers see a huge potential to keep their users from getting bored by offering new entertainment options while they are in the vehicle.
More Local Information
With the power of the internet and GPS your vehicle will be able to dynamically provide new information on wherever you go. You will be able to program your vehicle to notify you when you are near your favorite fast food joint, or if there is a location of interest close to your vehicle.
Everything from where the library is to the hippest restaurant in town can be brought up instantly as your driving. Imagine you are in a new city on business and feel hungry, so your car searches the internet, and recommends several different restaurants within 10 minutes of your location.
Here is another scenario, you are with your kids and want to find some where to stop to let them relax. You instruct your car to pull up and your application automatically finds the best places to take your kids within a 10 minute drive from your current location.
Safer Vehicles
Telematics is also leading to better road intelligence that is enabling both governments and drivers to make the road safer. There are several exciting new innovations such as:
> Analysis of statistical “black spots” that are dangerous for drivers and early warnings to slow down before you arrive
> Better data for local governments to make safer roads and adjust traffic systems to fit user demand
It is also encouraging users to drive safer by providing real time feedback on your driving. This is estimated to make the roads safer as a whole as drivers are corrected in real time for reckless driving.
Your vehicle will also be able to better adjust to road conditions when its data tells it that rain is coming up ahead. Your brakes, wheel sensitivity and more can all be adjusted to suit rainy conditions just before you arrive in the rainy location. This makes you safer while driving.
More Sophisticated Insurance
Telematics is estimated to become increasingly important to insurance providers as more users are expected to switch over to black box insurance. The types of insurance premiums offered through telematics will become increasingly sophisticated and differentiated.
For example we will see a change in telematics insurance options, you will no longer have to pick a single telematics insurance policy from your favorite provider. Instead you will have a wide range of new options such as basing your policy upon the number of miles you drive. You will be able to add on additional features such as extra country or mountainous miles which are more dangerous than city miles.
You will be able to pick specific policies catered to those who are in rush hour traffic everyday, and specialized policies that are for outdoor lovers. New telematics policies may take into account the year, condition, and make of your vehicle while assessing your driving and the road conditions you go on.
It is possible that future telematics insurance policies may offer you discounts for driving on country roads with a vehicle that is better suited for them. Or purchasing an extra safe vehicle could lead to lower costs even with a black box policy.
New options and choices will be important considerations for the conscious consumer as the insurance policies become more popular.
Ultimately telematics came out of the birth of GPS and is now enabling drivers everywhere to drive safer, more conveniently, and more intelligently. You are able to have greater entertainment, and be more productive on the road with the new innovations in telematics technology.
