Instructions For Connecting a Car MP3

If there basically is not a case huge to store all the CDs you require to take with you in the automobile, you may require to add an MP3 player. To play MP3 tunes in your automobile, you can get a used head unit that plays MP3 CDs, install a hard drive player, or hook up a transportable to your current stereo head unit.

I ever installed an FM modulator that hides behind the control panel and connects directly to the antenna and power, as against one that hangs down from the cigarette lighter. I followed the installation instructions that came with it. FM modulators of this type have an on-off switch for the antenna, which I put in a discreet place below the steering wheel.


The most straightforward route is to install a new head unit that plays MP3 and regular CDs. Most major aftermarket car stereo manufacturers offer MP3-compatible head units. You can transmit a lot of MP3-formatted songs on a CD, but this solution still entails carrying around CDs. You will also most likely require to have the unit professionally installed. When you are looking for an MP3-compatible head unit, make sure that it easily helps you navigate file and folders on your discs.

If you have a different brand of MP3 player, the cheapest solution uses an adapter that plugs into your car stereo's cassette player. But most new car stereos eschew cassettes can support CDs, so a cassette adapter may not be a choice. Another method is to get an adapter cable that plugs directly into your head unit. To go this route, your car stereo needs a spare input, such as an unused CD changer port. If you're not sure if you have an input available, you can check the owner's manual for your vehicle or stereo or look up your stereo or vehicle information online.

To install an adapter cable, you will need to plug it into the rear of the stereo by either removing the head unit or reaching under and behind the dashboard. Some head units come with an 1/8-inch auxiliary input mounted in their face. Do not block your rear view mirror monitor, with these solutions any of them, you will need to control your music selection from the MP3 player, as only the volume will be controllable from the car stereo itself.

Once you have connected, you'll possibly want a bracket or a cradle to hold your MP3 player so that you can see the screen. A wide variety are available, which mount to your windshield, your dashboard, and even your air vents. Choose a mounting method that makes the screen easy to view while you are driving but doesn't block the air bag or any of your dashboard functions.
