You should bench-test your VW radio before it is installed, especially if it is a used unit. This will save you from trying to troubleshoot it after it is installed in the cramped quarter of the vehicle’s dash. Bench-testing the VW radio is a straightforward process as speaker wiring is paired into colors that are standard across the industry. You can quickly bench-test the VW head unit with a few test leads, a spare speaker and a power source.
Things You’ll Need
- Roll of 12-gauge electrical wire
- Eight alligator clips
- Electrical pliers
- Audio test speaker
- Antenna with connector
- 12-volt car battery
1．Cut four, 2-foot jumper wires from the roll of electrical wire. Strip a half-inch of insulation from the ends of each wire with the electrical pliers.
2．Set the Android car stereo down, with the display facing you. Locate the four pairs of speaker wires: two white, left-front; two grey, right-front; two green, left-rear; two violet, right-rear. The solid-colored wires are positive; striped are negative.
3．Attach the end of one jumper wire to the positive wire of the test speaker with an alligator clip. Connect the other end of the jumper to the positive wire of the grey pair. Repeat with second jumper wire for the negative speaker wire.
4．Insert the antenna lead into the antenna socket on the stereo.
5．Attach one end of a third wire to the positive terminal of the battery with an alligator clip. Clip the other end of the wire to the red, yellow and orange wires coming from the stereo. Attach the fourth jumper wire to the stereo’s back grounding wire, and the other end to the battery’s negative terminal.
6．Turn on the stereo. Check the display for power. Adjust the volume control and left-right and front-rear fade controls while listening for the volume to fade in and out accordingly.
7．Turn the stereo off and move the jumper wires to the next pair or wires. Repeat for each pair of colored wires.

Bluetooth car stereos are commonly integrated with Bluetooth-enabled cell phones, and when the two devices are within range of each other, they can communicate in a number of interesting ways. Depending on the particular models in use, it may be possible to make and receive calls without even pulling out your phone or pushing a single button. You can even hear the calls through the vehicle’s speakers. Other models may require a few button-pushes, but usually with more ease than plodding through cell phone menus. You may also be able to view other information such as the phonebook, incoming calls and call status on the stereo panel. When the phone rings, the speakers will automatically turn down the volume on any music or movies that are playing while you chat on the phone and resume when the call is over.
Some Bluetooth car stereos can store your phone’s entire address book and other contact information; others have built-in phones which copy all the information off your phone’s SIM card and take over the functions for calling. Your cell phone is disconnected from the piconet, not only saving its battery power but also providing a stronger connection.
These innovations come almost as much out of necessity as convenience — at least for people who can’t stand being in the car without making a quick phone call. Many places now enforce laws limiting the use of cell phones while driving, and Bluetooth car stereos are one way to bridge the middle ground.
Besides augmenting your ability to connect with the outside world through phone calls, Bluetooth car stereos can also enhance the environment inside a vehicle. Transmitters can be used to stream music from iPods, MP3 players and satellite radio straight into the stereo without creating a mess of tangled cords. Some car stereos can display video on full-color LCD displays, although this usually isn’t an option when the car is moving. If you have some passengers in the back who could use a movie to settle down, lots of Bluetooth-enabled Android car stereos also come with the hookups needed to turn your vehicle into a mobile entertainment center. Connections for other devices like GPS navigators and USB flash drives are among other common fixtures.
And with each passing year, the technology grows and evolves. Comparing Bluetooth-enabled car stereos to cassette-enabled car stereos already seems like a throwback to the Middle Ages, so who knows what the future has in store.

I’ll give a review of Pumpkin JY-C0662T. The unit has a 6.2″ capacitive touch screen and is flanked by buttons on the two side. The buttons are pretty well laid out and are easily accessible.
Radio: This tuner sounds just as good if not better than my stock Toyota radio. There are your basic auto-scan (Scan) and preset buttons for the radio stations. There is a band button (on-screen) that chooses between AM, FM and RDS.
CD/DVD: There’s a slide in slot atop the radio for CD/DVD discs. Works as expected when you insert a CD it launches the CD player and plays the music. Basic seek and skip functionality is available and it also supports DVD video playback.
Navigation: The unit comes with GPS, and it functions much as you would expect. You plug in an address and it navigates a route there. You can also use Google Maps / Nav, which works but does require a data connection as the maps and routing are not done on the device, but rather online.
Wifi/ 3G data: There is a Wifi/ 3G cable that supports wifi (built-in) or 3G dongle (extra) to support data capabilities. If you have a phone that supports tethering, you can use it as your wifi data source.
Pandora & Google Apps: Because this is a true Android car head unit, it supports Pandora, Spotify and Google Music, and many other popular Google apps from the play store.
Bluetooth Phone & Audio: You can pair the stereo with your bluetooth phone or audio device, once paired you can do the following: Dial out and receive calls hands-free via the Mic. Your phone contacts can be downloaded into the unit.
Getting Android car stereo installed professionally will cost you a lot of money, and you’ve likely already spent quite a bit on purchasing the equipment.That’s why installing it yourself might be a good way to go. It’s entirely possible to do it all yourself, as long as you have the proper tools, wiring diagrams, and instructions. Depending on what you’ve purchased, it may also entail a significant time investment.
One very important point to remember: Always disconnect the negative connection on the car’s battery before you do any type of work to avoid shocking yourself or damaging your new equipment.
Installing coaxial speakers is fairly simple. These involve removing the front or rear factory speakers and simply swapping in the new ones while making sure the wiring is correct. Component speakers are a bigger job. Since you’re going to be putting multiple new parts in your car, like tweeters and woofers, this could involve some cutting or drilling into the doors or A-pillars. In some cases, you’ll need to be able to take apart your car door to accomplish this. The job may also involve some soldering. In addition, adding subwoofers to your car almost certainly means cutting holes in the trunk or rear compartment.
If you’re adding a new stereo receiver, that means you’ll need to remove the old one — usually by removing the bolts or even using special tools — then properly connecting the wires to the new head unit. Again, there may be wire cutting and soldering involved here, too. Your dashboard might also need to be modified to accommodate the new stereo if it’s a different size.
As a general rule, amps should be installed at least 3 feet (0.9 meters) from the receiver to prevent interference. The most popular method involves installing them under the seat or in the trunk. You’ll need to wire the amplifier into the car’s electrical system to power it, which can be complicated.
So what could go wrong if you install things incorrectly? A lot of things, actually. The speakers could be out of phase and sound distorted, you could cut the mounting point incorrectly and leave a gaping hole in your car door or you could wire it wrong and short out your electrical system. You run the risk of permanently damaging your car and your new stereo equipment if you do this wrong. In other words, unless you have the right tools, the right instructions, and the right experience, it may be worth the extra cost to have a professional install it.
