Technically, yes, it does eliminate the need for a PIE adapter. However, the sound quality is much better with the PIE. Be careful if you go the PIE route. When I got mine for my XM it needed a new chip, which took 2 weeks to get and their shipping left a lot to be desired. All the pins were bent, but I was able to bend them back. Then I started having other problems. One of the cable fell apart. I wish I would have gone with another brand instead of PIE.
