This is the complete kit that is needed to install an aftermarket Double Din radio into a Charger/Magnum with a Factory non Navigation radio installed. The entire set up includes the factory radio bezel, Double Din radio install trim kit, Wire Harness and Antenna Adapter. The Factory Radio Bezel is needed due to the fact that the factory radio opening in models with non Navigation radios are too small for the installation of a double din radio and therefore the entire bezel must be replaces with one equipped to install a Factory Navigation radio. The double din radio trim kit is then needed to reduce the size of the Factory Navigation bezel to the proper size of an aftermarket double din radio. This trim kit is designed specifically for the charger and magnum lining up with factory mounting to install and uninstall easily. There are no modifications necessary. The wire harness meets EIA color code to take the guess work out of installing an aftermarket radio. Designed to prevent the mess of cutting and splicing wires the existing indash male wire harness can be inserted into this female wire harness after it is wired to the new aftermarket radio. If you sell your vehicle simply unplug the aftermarket radio and replug the factory radio back in. The antenna adapter is used to adapt the factory antenna end to the standard male end needed to install an aftermarket radio. This adapter may not work if you have installed an aftermarket antenna as most do not require adaptation.
