  ...The Best Place to Buy a Stereo For Your Semi Online

We understand the importance of having a high quality heavy duty stereo in the cab. Driving without music or with a malfunctioning GPS system is no fun at all. We have what you need to resolve your stereo or navigation system woes.

When upgrading the stereo in Freightliner, International, Kenworth, Peterbilt, Mack or other tractor, choose one of our Aptiv or Pro-Audio Heavy-Duty Stereos as these are built specifically for semi trucks.

Installing one of our stereos in just about any semi-truck or other tractor is incredibly simple. You should never have to cut and splice wires that's why we supply a free Plug n' Play wire harness with all of our stereos. We'll collect your vehicle details to ensure you receive the correct wire-harness if any is required. This also gives us a chance to review the stereo compatibility with your specific semi for retention of steering wheel control, sleeper control and so on.

Replacing SmartNav™ & NavPlus™ Systems. We offer both OEM 2nd Generation systems which are drop in replacements for the original equipment. Please see appropriate model for your Peterbilt SmartNav or Kenworth NavPlus System

Is it a Stereo or a Radio?

Have you ever wondered why some people say radio and others say stereo? It's a little confusing since many people use the two words interchangeably, but they're not really the same. A radio is a transmission device used for sound and other signals by the modulation of electromagnetic waves. A stereo is used for reproducing sound. It uses two channels, each plays a portion of the original sound.
