Modern cars feature space for double DIN stereo. So, if you are replacing the older double DIN unit with a new and upgraded model, then installation will be super easy. All the double DIN head systems are of the same size. For installation, you need to check the manual that is shipped with the product. You only need to fit the system into the dashboard. Installation does not need tools or professional mechanics. However, if you are replacing the single DIN unit with a double DIN stereo system, then the installation can be a little difficult.
