Evolution of Head Units

If u were to ask an audiophile the importance of a Head Unit, you would probably get answer that it is the BRAIN of any Car Entertainment System. It is a single point interface between you and your system and the head unit makes up for almost 50-70% of the total cost of a car entertainment system. This important part has undergone an evolution since its introduction.

The term head unit did not exist before 1990's as all the cars on the road had a tape or a radio fitted by the car manufacturer, but in 1991 Alpine introduced the first after-market DAT (Digital Audio Tape) head unit. Since then there was seen a rise in the demand for after-market head units as the were more affordable and available as per choice (something we still do today). For today's car buyers the total experience of a car is not just limited to its driveability only. we look at many more aspects one of which is the in-built car entertainment system.

There is no specific generation mapping of the head units but we have gone ahead and tried to do so.

GEN 1

The 1st Gen head unit was a 1 DIN head unit which had capability of playing the Audio Tapes and Radio tuning.

 

GEN 2

The 2nd Gen was of 1 DIN head units with CD player along with better audio tuning ability and to play Audio Tapes and have an arrangement of attaching a CD changer. A small device CD to cassette converter provided way for playing through disc-man but it always had a problem of high distortion.

 

GEN 3

The 3rd Gen head units had the ability to play MP3 CD's along with the radio tuning and more advanced sound system could be attached to give a complete audio experience. By this time the use Audio Tapes had lost out on its reach to people. There was introduction of AUX support.

GEN 4

The 4th Gen head units had VCD,DVD playback capability and also there was an introduction of 2DIN head units for MP3 playback. VCD and DVD required a separate monitor for display. This era saw the front Aux and USB support.

GEN 5

The 5th Gen got over the faults of 4th gen and there was in integration of DVD, USB, AUX and card reader ability along with the display in the 2DIN head unit itself. There was little change in comparison to 4th gen but this era was the headline for the next gen as there was for first time a 2DIN system with video display capability.

Today we are in 6th Gen in which we no longer call it a head unit but a new term is born "Car Multimedia Receiver". Its kinda complex but if you are to have a look at all the features it offers then it is quite apt. There is more emphasis on enhancing the entire experience by providing better UI (User Interface) and Superior Display and loadsa other features. Like

- Ipod/ Iphone connectivity

- USB/ Card reader

- Touch UI

- OLED Display

- Bluetooth

- Navigation and much more

When it comes to buying a new car we all face a similar problem, many a times the head units offered by the manufacturer are too basic and at times spoil the look of the center console. Like in the case when i was buying a Toyota Innova the top variant had a head unit which was utterly disgustiing for a car worth 12 lacs. The only way out was something which was being done since early 1990's and go for after-market Car Multimedia System.

Here are some of the best Car Multimedia Systems available in the market.

Formula 1, what’s the fuss all about!

The F1 logo...the 'F' and '1' also make a one in the spacing between them! 

   Formula 1 for those who don’t follow it, is so-called ‘sport’ where they make weird looking cars go round and round, some guys crash and some go in a separate lane and get theirs tyres changed super-fast...and the one who is at the foremost of the pack wins and does some showboating by spraying champagne on people around him. And well if now you are thinking ‘holy cow, this guy reads my mind! Isn’t this all what F1 is ?!’ then my naive friend you absolutely need to have a through look at this article!

   F1 is the final word when it comes to technology, team spirit, physical fitness levels and big money along with lavish lifestyles! This entire saga began in 1951 when the first official F1 championship was held...well it wasn't a very big commercial avenue like today. It was more of manufactures like Mercedes, Ferrari, Alfa Romeo, Maserati and even some private players coming together pitting their machines against one and other with a pack of very gutsy drivers to help them achieve glory. As the rules kept changing the cars began evolving along with the sport and today we have around 800bhp monsters which can reach speeds of up to 340 kmph, accelerate from standstill to a 100 kmph in 1.7 secs and 200 in 3.8 secs and touch 300 in around 9 seconds! And can pull almost 5 G of force and just weigh around 650-700 kgs.

   All this is possible only by continuous development, heavy investments and a passion to strive for the best. These factors are solely responsible for the sport to be at the pinnacle of technology and these innovations eventually trickle down to passenger cars making them faster, more fun and safer to drive. Most of the automotive technologies that we are used to have come from F1...from ABS to active suspension the credit goes to Formula 1. Currently F1 uses a KERS system; it stands for Kinetic Energy Recovery System...all this jargon means that the kinetic energy of the moving vehicle which is wasted in the form of heat while braking is converted into electric energy and is stored. This energy can be used by the driver as boost of 60-90 bhp for duration of 6 seconds. A couple of decades down the line, when your son will be insisting on a sexy looking electric saloon, I am pretty sure that today’s KERS inspired tech will be the backbone of that car!

Here's an amazing animated video, explaining the KERS system and also the DRS (Drag Reduction System) in detail..

  And well, to be able to handle and make all this technology work in perfect harmony the driver acts as the pivot...and despite all this even today the most advanced F1 car is nothing without a deserving driver. But we will have more on that later, a small paragraph wouldn’t do justice to this different breed of humans...they deserve an entire article! What makes a race interesting and much more than 24 cars going round and round, are multitude of factors ,some controllable and some not. This year the new Pirelli tyres have shaken things up considerably with their short life span...this has resulted in more pit-stops and thus race strategy becomes more prominent. Many places have been lost and gained just because of botched pit-spot strategy and has won drivers races where it seemed to be impossible to overtake on the track.  And this is just the tip of the iceberg, weather conditions, car setups, mechanical and electrical gremlins and many more factors are able to maintain the air of uncertainty until the chequered flag is waved and the driver crosses the finishing line.

The driver's one has the names of all the previous champions engraved in a spiral starting from the bottom; the contructors champs have their badges stuck on in strategic positions - look closely and you can see the Ferrari, Lotus and Cooper emblems.

   As of now almost half of the 2011 season is over, last year’s constructors’ champion Red Bull Racing is still dominating and Sebastian Vettel is still leading the current championship table. Today the race is held at Nurburgring in Germany, it’s the 10^th race of the season out of the total 19 races. An interesting fact to note is that this time ‘round, 25% of the drivers on the grid are German! So the pressure to perform in front of the home crowd would be immense, but drivers say that it acts more as a motivation to them. And another thing that is out of the ordinary is that, the turns 8 and 9 in the Nurburgring track had been christened as the ‘Schumacher S’ after Michael Schumacher retired in 2006...he made a heroic comeback to F1 last year, and I think it’s the first time a driver would race on corners named after him...what pride! After yesterdays qualifying,  Mark Webber has taken the pole and Lewis Hamilton is 2nd on the grid with Vettel 3rd and the Ferraris of Alonso and Massa not far behind.  The earlier half of the season was largely dominated by Red Bull and the closest contenders Mc'Laren Mercedes and Ferrari were lagging behind a lot. But of-late they have caught up and have brought the fight to the defending champions.With all 3 top performing teams pretty closely tied, it sure makes for a very tantalizing race ahead with rain forecasts, victory could be anybody's bet!    

   So now what are you waiting for! Sunday 5:30 pm do switch over to Star Sports or ESPN HD (if you are the few lucky ones to receive that channel, unfortunately I am not) and enjoy the broadcast of the German Grand Prix live. If speed, technology, super-human driving skills, sportsmanship, ‘clockwork precision’ team work gratify you like cocktail waitresses gratify Tiger Woods...join the band-wagon and dive head first into the realm of Formula 1...
