This is everything you need to connect an aftermarket stereo to a Volkswagen. This comes with a fully wired harness secured with wire caps, a reverse camera retention set up, a satellite antennae adapter, microphone, backup camera, and a steering wheel control interface. I used this harness for a few days and when I got a new stereo it came with its own harness so I switched them out. The harness works perfectly and everything connects as it should. Supports - Apple Carplay/Android Auto - Using steering wheel buttons to control stereo - AM/FM satellite radio - Rear view camera - Microphone to use handsfree calling and Siri Open to negotiations. I also have other stereo parts and wiring items listed for sale on my page. If you are buying more than one Item I will throw deals and lower prices. The other items I have - Boss HD Backup Camera Mount Kit - PAC Steering Wheel Interface - Boss be7acp Microphone - Backup Camera Retention for Volkswagen - Brand New Backup/Dash Camera - OEM Volkswagen Touchscreen Stereo - OEM Volkswagen Stereo with CD Player
