Exact Vehicle Compatibility

Find your vehicle below, then match the model year and factory-equipment details in the same row. Factory radio, amplifier, navigation, trim, speaker location, and connector differences can change which installation parts are required. If anything differs, contact MCOR before ordering.

Fitment note: Year and model alone are not always enough to confirm compatibility. Match every factory-equipment qualifier shown for your vehicle, and contact MCOR Automotive if the radio, amplifier, navigation, speaker, camera, trim, or connector details are uncertain.

Installation Notes

• Confirm exact year, make, model, factory radio, and antenna connector before installation.
• Match the adapter direction to the installation type: aftermarket radio, factory radio, aftermarket antenna, or FM modulator.
• Additional radio installation parts may be required depending on the vehicle and head unit.
• Professional installation is recommended for proper antenna integration and signal performance.
