Questions about this item

Does the EH4866AR0 unit come with a mounting kit and wiring harness, or must those be purchased separately?

The unit is sold as the radio and CD player only; any dash kit, antenna adapter or wiring harness required for installation must be sourced separately.

How do I confirm the EH4866AR0 or interchange number 638-51977 is the correct version for my 2011-2012 Mazda CX-7?

Match the part number printed on your original radio to EH4866AR0 or 638-51977; even visually identical units can have different data streams or external-amplifier configurations that prevent coding.

What does the 100% functional rating mean for daily use of the AM/FM single-disc CD player?

It indicates the remanufactured unit has been cleaned, serviced and tested so that radio reception, CD playback and all faceplate controls operate as intended in the vehicle.
