This is the complete kit that is needed to install a aftermarket Double Din radio into your vehicle with a Factory non Navigation radio installed. This entire set up includes the factory radio bezel (part# XB311ZBAA),wiring harness and Antenna Adapter. This dash kit is designed specifically for your vehicle, it lines up with factory mounting to install and uninstall easily, in-case you decide to sell your vehicle it can go right back to factory. There are no modifications necessary. The Wire harness provides easy connection of the car stereo to the factory wiring harness. Harness includes both power and speaker wires, and each is labeled with its specific function. Any cutting of the factory wires is avoided so all connections are exactly right. All wires are color coded (EIA standard) for easy identification. This wiring harness allows models with Factory Amplified Systems to replace REF, REC, RAQ and RAK factory radios while retaining all necessary safety and warning features. The radio’s name can be found on the face of the radio and the amplifier is usually branded Alpine, Boston Acoustic, Infinity or Kicker. The antenna adapter is used to adapt the factory antenna end to the standard Motorola male end need to plug in to your new aftermarket radio. This plug may not work if you have installed an aftermarket antenna, as most of those do not require adaptation. There are no modifications necessary.
