VW Wiring (1998 And Later Models)

The radios in VW cars (1998 model and onwards) use an amplified aerial for improved radio reception. This amplifier is built into the base of the aerial and is powered by a feed from the stereo. This power feed is sent down the center of the aerial cable.

Therefore, if the factory-fitted stereo is replaced with an aftermarket unit, the aerial will no longer get this power feed and the amplifier in the aerial will not be turned on. This will result in poor radio reception.

To solve this problem you will need a VW aerial adapter. This takes the electric aerial output of an aftermarket stereo and combines it with the aerial socket to supply power to the amplifier in the aerial.

The other difference that post 1998 Volkwagen car radios have is their power connection. . .

Stereos require 2 power feeds. One is a constant feed that is always live whether you have the key in the ignition or not (this keeps the memory settings, clock etc). The other is a switched live which gets a feed when the ignition key is turned.

Although VW car radios use an ISO connection block for their stereo wiring (the same as all aftermarket stereos) you cannot simply plug it straight in. On later Volkswagen car radios, the pin configuration of these two power wires is reversed. If you plug it straight in, the stereo will work fine. However, it will lose all of it's memory settings once you switch it off.

To solve this problem, you will need a VW wiring adaptor. This will plug into your VW wiring harness at one end and the aftermarket stereo at the other end. In between these two points, the adaptor swaps over the location of the two power wires. This takes care of the problem.

This store specializes in car audio. I give them thumbs up -- I work with them daily (so I know their business philosophy -- customer satisfaction) . However, if your country is not served by them, you can still get other recommendations at car-audio-products-and-accessories.com

Electrical Engineering Careers

If you are interested in becoming an electrical engineer, there are many electrical engineering careers that are excellent career choices. While becoming an electrical engineer can take a bit of schooling, studying, and hard work, the variety of electrical engineering careers that are available often make it worth the years of working towards the goal. If you are considering getting an electrical engineering degree, you may want to take a look at the electrical engineering careers that are available once you complete your training.

Digital Technology

One of the many electrical engineering careers includes working with digital technology. This career allows electrical engineers to work with digital technology and to develop ways to make digital technology small enough to be easy to use. Workers in this career may be able to work with cell phone companies to make the required technology small enough to fit into the smallest cell phone or they may design technology to make cell phones more efficient. This can be an exciting career for an electrical engineer and can be quite lucrative as well.

Power Engineering

Another of the many electrical engineering careers is power engineering. This type of a career deals with working with power and electricity and transmitting, generating, and distributing this power effectively. This career requires working with generators, motors, transformers, and even power electronics. While this can be a dangerous job at times, it can be very exciting and rewarding for an electrical engineer.

Computer Engineering

Electrical engineering careers also include computer engineering, as well. While electrical engineers do not actually design the software for computers, they often design the hardware and electrical technology that makes them run effectively. If you enjoy working with computers and want an electrical engineering degree, this is one of the electrical engineering careers that you may enjoy.

Control Engineering

Another of the electrical engineering careers that are available for those with an electrical engineering degree is control engineering. This career involves working with controllers to make entire systems work in a particular manner. Electrical circuits, PLCs, micro controllers, and digital signal processors are often used for this job. Many people in this specific field actually end up working for NASA and working with the systems and controls for space shuttles. This can be one of the most exciting electrical engineering careers that are available for electrical engineers.

Electronic Engineering

Electrical engineering careers are also available in electronic engineering for those who are electronic engineers. In this career field, electronic engineers not only design electronic circuits, but they also test them, as well. Those who choose electrical engineering careers in this field work with radios, computers, and modern television systems on a regular basis. This can be a very rewarding and interesting career to pursue.

These are just a few of the electrical engineering careers that are available once you get a degree in electrical engineering. There are always career options for electrical engineers, so getting a degree in this field guarantees you a job in a field related to your interests.
