This is a Peripheral PXVWHF2 (now part of the PAC Audio HFKVW2-P) handsfree integration harness. These are in new condition, though some may not be in their original packaging. This adapter fits many 1999-2008-ish VW vehicles with the Double DIN radios that support a telephone mute and phone audio input . This PXVWHF2 harness will connect directly to certain Motorola IHF1000 / 1500 / 1700 / T605 carkit harnesses. An additional adapter may be required to connect to Parrot and other carkits. I have a mobile electronics installation business, and am selling off some excess inventory. Please feel free to send a message if you have further questions about any of my items. Thanks for looking!
