A modern stereo system doesn't rely on satellite radio or other gimmicks to help you listen to the music that you like. All you need to do is plug your phone or other mobile device into your car to start listening to your custom playlists. As soon as you turn on your car, you can listen to the music that you choose instead of having to listen to the music selected for you by a computer.
This means that you don't have to constantly change the stations or listen to a station that has music that is supposedly related to songs that you like. When you have a custom sound system installed by Pacific Stereo or another accessory shop, you know that you are going to get the best sound, the ease of listening to the music that you like and the assurance that you will get it for the best price.
