Review on Enhance Your Sony System: MicroBypass Parking Brake Override Bypass for Sony by Daryl Fitch

Good grounding solution for Sony radios. After reading various forums I tried to ground the wire that needs to be grounded for the parking brake to the metal frame in the car and it didn't work. I couldn't connect my phone to Android Auto. After purchasing this bypass, the phone now connects every time. The three wires are color coded and, with a little logic, are fairly easy to connect to the receiver's wiring. I would suggest testing the device before final installation to make sure everything is working properly.
