For example, external amps are used in some cars and will not allow interchange, etc. No codes required, it will plug and play! *** Although this radio will be unlocked upon installation, please note that if you have Bose or any other specialty sound system, you may have to visit a dealer to get this radio configured properly for your vehicle. *** Please feel free to give us a call with any questions or concerns. *Please note: that the radio is unlocked only upon first installation. Once it has been paired to your vehicle's VIN, you will need to get it unlocked upon installation in another vehicle.
