CR4000A preserves a healthy status in internal diagnostics by sending the proper data commands to your vehicle's ECM (Electronics Control Module). CR4000A works properly with factory CAN Bus Data Systems. Also includes: a red +12V switched accessory power source for aftermarket stereos. *Includes harness

Why do I need to spend extra on an interface?An interface is a small computer system that allows your new head unit to properly communicate with your vehicle’s computer system. If you install a new aftermarket radio without using an interface, you will lose many of the standard security features of the vehicle. This is due to vehicle manufactures running part of the vehicle’s computer system through the OEM radio. Functions lost include, but not limited to, are warning chimes (keys left in ignition, lights left on, low fuel etc.), security and alarm systems, +12V accessory and more. If the +12V accessory is lost, your radio will not turn on/off automatically and will be a manual process.
