This interface allows you to upgrade your Mazda CX-7 or CX-9 sound system with an aftermarket radio. The custom design includes 4-channel RCA inputs for easy connection and allows you to replace an OEM unit while retaining the BOSE® system.
Q: Does this work for vehicles WITHOUT the Bose system?
A: This wiring harness is for a car that has bose as a factory installed radio. Not sure if it will work for other brands.
