Very nice RNS510 removed from a 2015 Passat that was totalled with 160k miles. Radio is in great shape. It is on the original firmware & installed maps. Code is written on the radio. It is currently programmed for DYNAUDIO, unsure if reverse camera (RVC) is activated or not. Will require programming to your specific car's audio system using VCDS/Vagcom, obd11 etc.
Please confirm fitment before purchase. MyTurboDiesel has some good articles if you're retrofitting one.
