I've had my PP for only a few days, so my likes are plenty and dislikes are few. This thing is quiet! It replaced an Outback 3.6 Limited, which I thought was quiet, which it was, but the Passport is even better. Also, the sound system is fairly impressive. I do not use CarPlay, since that employs the iPhone's horrible 1-bit DAC, and the sound quality suffers. I use an outboard 24-bit DAC, which sounds tons better and takes full advantage of the sound system's abilities. I lose the song info displayed on the dash, but sound quality is more important.
